Struct url2::Url2

pub struct Url2(_);

Ergonomic wrapper around the popular Url crate

Implementations

impl Url2

pub fn try_parse<S: AsRef<str>>(s: S) -> Url2Result<Self>

Try to parse a utf8 slice into a Url2 instance. May result in a UrlParseError

Example

use url2::prelude::*;

assert_eq!(
    "Err(Url2Error(UrlParseError(RelativeUrlWithoutBase)))",
    &format!("{:?}", Url2::try_parse("")),
);
assert_eq!(
    "Ok(Url2 { url: \"none:\" })",
    &format!("{:?}", Url2::try_parse("none:")),
);

pub fn parse<S: AsRef<str>>(s: S) -> Self

Try to parse a utf8 slice into a Url2 instance. If this results in a UrlParseError, this method will panic!

Example

use url2::prelude::*;

assert_eq!("none:", Url2::parse("none:").as_str());

pub fn into_string(self) -> String

convert this Url2 instance into a string

Example

use url2::prelude::*;

assert_eq!("none:", Url2::default().as_str());

pub fn query_unique(&mut self) -> Url2QueryUnique<'_>

Access query string entries as a unique key map.

Url query strings support multiple instances of the same key However, many common use-cases treat the query string keys as unique entries in a map. An optional API viewing the query string in this manner can be more ergonomic.

The HashMap that backs this view is only created the first time this function (or the following query_unique_* functions) are invoked. If you do not use them, there is no additional overhead.

Example

use url2::prelude::*;

let mut url = Url2::default();
url.query_unique().set_pair("a", "1").set_pair("a", "2");

assert_eq!("none:?a=2", url.as_str());

pub fn query_unique_contains_key(&mut self, key: &str) -> bool

When parsed as a unique map, does the query string contain given key?

Example

use url2::prelude::*;

let mut url = Url2::parse("none:?a=1");

assert!(url.query_unique_contains_key("a"));
assert!(!url.query_unique_contains_key("b"));

pub fn query_unique_get(&mut self, key: &str) -> Option<&str>

When parsed as a unique map, get the value for given key

Example

use url2::prelude::*;

let mut url = Url2::parse("none:?a=1");

assert_eq!(
    "Some(\"1\")",
    &format!("{:?}", url.query_unique_get("a")),
);
assert_eq!(
    "None",
    &format!("{:?}", url.query_unique_get("b")),
);

Methods from Deref<Target = Url>

pub fn join(&self, input: &str) -> Result<Url, ParseError>

Parse a string as an URL, with this URL as the base URL.

Note: a trailing slash is significant. Without it, the last path component is considered to be a “file” name to be removed to get at the “directory” that is used as the base:

Examples

use url::Url;

let base = Url::parse("https://example.net/a/b.html")?;
let url = base.join("c.png")?;
assert_eq!(url.as_str(), "https://example.net/a/c.png");  // Not /a/b.html/c.png

let base = Url::parse("https://example.net/a/b/")?;
let url = base.join("c.png")?;
assert_eq!(url.as_str(), "https://example.net/a/b/c.png");

Errors

If the function can not parse an URL from the given string with this URL as the base URL, a ParseError variant will be returned.

pub fn as_str(&self) -> &str

Return the serialization of this URL.

This is fast since that serialization is already stored in the Url struct.

Examples

use url::Url;

let url_str = "https://example.net/";
let url = Url::parse(url_str)?;
assert_eq!(url.as_str(), url_str);

pub fn origin(&self) -> Origin

Return the origin of this URL (https://url.spec.whatwg.org/#origin)

Note: this returns an opaque origin for file: URLs, which causes url.origin() != url.origin().

Examples

URL with ftp scheme:

use url::{Host, Origin, Url};

let url = Url::parse("ftp://example.com/foo")?;
assert_eq!(url.origin(),
           Origin::Tuple("ftp".into(),
                         Host::Domain("example.com".into()),
                         21));

URL with blob scheme:

use url::{Host, Origin, Url};

let url = Url::parse("blob:https://example.com/foo")?;
assert_eq!(url.origin(),
           Origin::Tuple("https".into(),
                         Host::Domain("example.com".into()),
                         443));

URL with file scheme:

use url::{Host, Origin, Url};

let url = Url::parse("file:///tmp/foo")?;
assert!(!url.origin().is_tuple());

let other_url = Url::parse("file:///tmp/foo")?;
assert!(url.origin() != other_url.origin());

URL with other scheme:

use url::{Host, Origin, Url};

let url = Url::parse("foo:bar")?;
assert!(!url.origin().is_tuple());

pub fn scheme(&self) -> &str

Return the scheme of this URL, lower-cased, as an ASCII string without the ':' delimiter.

Examples

use url::Url;

let url = Url::parse("file:///tmp/foo")?;
assert_eq!(url.scheme(), "file");

pub fn has_authority(&self) -> bool

Return whether the URL has an 'authority', which can contain a username, password, host, and port number.

URLs that do not are either path-only like unix:/run/foo.socket or cannot-be-a-base like data:text/plain,Stuff.

Examples

use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.has_authority());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.has_authority());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(!url.has_authority());

pub fn cannot_be_a_base(&self) -> bool

Return whether this URL is a cannot-be-a-base URL, meaning that parsing a relative URL string with this URL as the base will return an error.

This is the case if the scheme and : delimiter are not followed by a / slash, as is typically the case of data: and mailto: URLs.

Examples

use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(!url.cannot_be_a_base());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.cannot_be_a_base());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(url.cannot_be_a_base());

pub fn username(&self) -> &str

Return the username for this URL (typically the empty string) as a percent-encoded ASCII string.

Examples

use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.username(), "rms");

let url = Url::parse("ftp://:secret123@example.com")?;
assert_eq!(url.username(), "");

let url = Url::parse("https://example.com")?;
assert_eq!(url.username(), "");

pub fn password(&self) -> Option<&str>

Return the password for this URL, if any, as a percent-encoded ASCII string.

Examples

use url::Url;

let url = Url::parse("ftp://rms:secret123@example.com")?;
assert_eq!(url.password(), Some("secret123"));

let url = Url::parse("ftp://:secret123@example.com")?;
assert_eq!(url.password(), Some("secret123"));

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.password(), None);

let url = Url::parse("https://example.com")?;
assert_eq!(url.password(), None);

pub fn has_host(&self) -> bool

Equivalent to url.host().is_some().

Examples

use url::Url;

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.has_host());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(!url.has_host());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(!url.has_host());

pub fn host_str(&self) -> Option<&str>

Return the string representation of the host (domain or IP address) for this URL, if any.

Non-ASCII domains are punycode-encoded per IDNA. IPv6 addresses are given between [ and ] brackets.

Cannot-be-a-base URLs (typical of data: and mailto:) and some file: URLs don’t have a host.

See also the host method.

Examples

use url::Url;

let url = Url::parse("https://127.0.0.1/index.html")?;
assert_eq!(url.host_str(), Some("127.0.0.1"));

let url = Url::parse("ftp://rms@example.com")?;
assert_eq!(url.host_str(), Some("example.com"));

let url = Url::parse("unix:/run/foo.socket")?;
assert_eq!(url.host_str(), None);

let url = Url::parse("data:text/plain,Stuff")?;
assert_eq!(url.host_str(), None);

pub fn host(&self) -> Option<Host<&str>>

Return the parsed representation of the host for this URL. Non-ASCII domain labels are punycode-encoded per IDNA.

Cannot-be-a-base URLs (typical of data: and mailto:) and some file: URLs don’t have a host.

See also the host_str method.

Examples

use url::Url;

let url = Url::parse("https://127.0.0.1/index.html")?;
assert!(url.host().is_some());

let url = Url::parse("ftp://rms@example.com")?;
assert!(url.host().is_some());

let url = Url::parse("unix:/run/foo.socket")?;
assert!(url.host().is_none());

let url = Url::parse("data:text/plain,Stuff")?;
assert!(url.host().is_none());

pub fn domain(&self) -> Option<&str>

If this URL has a host and it is a domain name (not an IP address), return it.

Examples

use url::Url;

let url = Url::parse("https://127.0.0.1/")?;
assert_eq!(url.domain(), None);

let url = Url::parse("mailto:rms@example.net")?;
assert_eq!(url.domain(), None);

let url = Url::parse("https://example.com/")?;
assert_eq!(url.domain(), Some("example.com"));

pub fn port(&self) -> Option<u16>

Return the port number for this URL, if any.

Note that default port numbers are never reflected by the serialization, use the port_or_known_default() method if you want a default port number returned.

Examples

use url::Url;

let url = Url::parse("https://example.com")?;
assert_eq!(url.port(), None);

let url = Url::parse("https://example.com:443/")?;
assert_eq!(url.port(), None);

let url = Url::parse("ssh://example.com:22")?;
assert_eq!(url.port(), Some(22));

pub fn port_or_known_default(&self) -> Option<u16>

Return the port number for this URL, or the default port number if it is known.

This method only knows the default port number of the http, https, ws, wss, ftp, and gopher schemes.

For URLs in these schemes, this method always returns Some(_). For other schemes, it is the same as Url::port().

Examples

use url::Url;

let url = Url::parse("foo://example.com")?;
assert_eq!(url.port_or_known_default(), None);

let url = Url::parse("foo://example.com:1456")?;
assert_eq!(url.port_or_known_default(), Some(1456));

let url = Url::parse("https://example.com")?;
assert_eq!(url.port_or_known_default(), Some(443));

pub fn socket_addrs(
    &self,
    default_port_number: impl Fn() -> Option<u16>
) -> Result<Vec<SocketAddr>, Error>

Resolve a URL’s host and port number to SocketAddr.

If the URL has the default port number of a scheme that is unknown to this library, default_port_number provides an opportunity to provide the actual port number. In non-example code this should be implemented either simply as || None, or by matching on the URL’s .scheme().

If the host is a domain, it is resolved using the standard library’s DNS support.

Examples

let url = url::Url::parse("https://example.net/").unwrap();
let addrs = url.socket_addrs(|| None).unwrap();
std::net::TcpStream::connect(&*addrs)

/// With application-specific known default port numbers
fn socket_addrs(url: url::Url) -> std::io::Result<Vec<std::net::SocketAddr>> {
    url.socket_addrs(|| match url.scheme() {
        "socks5" | "socks5h" => Some(1080),
        _ => None,
    })
}

pub fn path(&self) -> &str

Return the path for this URL, as a percent-encoded ASCII string. For cannot-be-a-base URLs, this is an arbitrary string that doesn’t start with '/'. For other URLs, this starts with a '/' slash and continues with slash-separated path segments.

Examples

use url::{Url, ParseError};

let url = Url::parse("https://example.com/api/versions?page=2")?;
assert_eq!(url.path(), "/api/versions");

let url = Url::parse("https://example.com")?;
assert_eq!(url.path(), "/");

let url = Url::parse("https://example.com/countries/việt nam")?;
assert_eq!(url.path(), "/countries/vi%E1%BB%87t%20nam");

pub fn path_segments(&self) -> Option<Split<'_, char>>

Unless this URL is cannot-be-a-base, return an iterator of '/' slash-separated path segments, each as a percent-encoded ASCII string.

Return None for cannot-be-a-base URLs.

When Some is returned, the iterator always contains at least one string (which may be empty).

Examples

use url::Url;

let url = Url::parse("https://example.com/foo/bar")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some("foo"));
assert_eq!(path_segments.next(), Some("bar"));
assert_eq!(path_segments.next(), None);

let url = Url::parse("https://example.com")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some(""));
assert_eq!(path_segments.next(), None);

let url = Url::parse("data:text/plain,HelloWorld")?;
assert!(url.path_segments().is_none());

let url = Url::parse("https://example.com/countries/việt nam")?;
let mut path_segments = url.path_segments().ok_or_else(|| "cannot be base")?;
assert_eq!(path_segments.next(), Some("countries"));
assert_eq!(path_segments.next(), Some("vi%E1%BB%87t%20nam"));

pub fn query(&self) -> Option<&str>

Return this URL’s query string, if any, as a percent-encoded ASCII string.

Examples

use url::Url;

fn run() -> Result<(), ParseError> {
let url = Url::parse("https://example.com/products?page=2")?;
let query = url.query();
assert_eq!(query, Some("page=2"));

let url = Url::parse("https://example.com/products")?;
let query = url.query();
assert!(query.is_none());

let url = Url::parse("https://example.com/?country=español")?;
let query = url.query();
assert_eq!(query, Some("country=espa%C3%B1ol"));

pub fn query_pairs(&self) -> Parse<'_>

Parse the URL’s query string, if any, as application/x-www-form-urlencoded and return an iterator of (key, value) pairs.

Examples

use std::borrow::Cow;

use url::Url;

let url = Url::parse("https://example.com/products?page=2&sort=desc")?;
let mut pairs = url.query_pairs();

assert_eq!(pairs.count(), 2);

assert_eq!(pairs.next(), Some((Cow::Borrowed("page"), Cow::Borrowed("2"))));
assert_eq!(pairs.next(), Some((Cow::Borrowed("sort"), Cow::Borrowed("desc"))));

pub fn fragment(&self) -> Option<&str>

Return this URL’s fragment identifier, if any.

A fragment is the part of the URL after the # symbol. The fragment is optional and, if present, contains a fragment identifier that identifies a secondary resource, such as a section heading of a document.

In HTML, the fragment identifier is usually the id attribute of a an element that is scrolled to on load. Browsers typically will not send the fragment portion of a URL to the server.

Note: the parser did not percent-encode this component, but the input may have been percent-encoded already.

Examples

use url::Url;

let url = Url::parse("https://example.com/data.csv#row=4")?;

assert_eq!(url.fragment(), Some("row=4"));

let url = Url::parse("https://example.com/data.csv#cell=4,1-6,2")?;

assert_eq!(url.fragment(), Some("cell=4,1-6,2"));

pub fn set_fragment(&mut self, fragment: Option<&str>)

Change this URL’s fragment identifier.

Examples

use url::Url;

let mut url = Url::parse("https://example.com/data.csv")?;
assert_eq!(url.as_str(), "https://example.com/data.csv");
url.set_fragment(Some("cell=4,1-6,2"));
assert_eq!(url.as_str(), "https://example.com/data.csv#cell=4,1-6,2");
assert_eq!(url.fragment(), Some("cell=4,1-6,2"));

url.set_fragment(None);
assert_eq!(url.as_str(), "https://example.com/data.csv");
assert!(url.fragment().is_none());

pub fn set_query(&mut self, query: Option<&str>)

Change this URL’s query string.

Examples

use url::Url;

let mut url = Url::parse("https://example.com/products")?;
assert_eq!(url.as_str(), "https://example.com/products");

url.set_query(Some("page=2"));
assert_eq!(url.as_str(), "https://example.com/products?page=2");
assert_eq!(url.query(), Some("page=2"));

pub fn query_pairs_mut(&mut self) -> Serializer<'_, UrlQuery<'_>>

Manipulate this URL’s query string, viewed as a sequence of name/value pairs in application/x-www-form-urlencoded syntax.

The return value has a method-chaining API:

let mut url = Url::parse("https://example.net?lang=fr#nav")?;
assert_eq!(url.query(), Some("lang=fr"));

url.query_pairs_mut().append_pair("foo", "bar");
assert_eq!(url.query(), Some("lang=fr&foo=bar"));
assert_eq!(url.as_str(), "https://example.net/?lang=fr&foo=bar#nav");

url.query_pairs_mut()
    .clear()
    .append_pair("foo", "bar & baz")
    .append_pair("saisons", "\u{00C9}t\u{00E9}+hiver");
assert_eq!(url.query(), Some("foo=bar+%26+baz&saisons=%C3%89t%C3%A9%2Bhiver"));
assert_eq!(url.as_str(),
           "https://example.net/?foo=bar+%26+baz&saisons=%C3%89t%C3%A9%2Bhiver#nav");

Note: url.query_pairs_mut().clear(); is equivalent to url.set_query(Some("")), not url.set_query(None).

The state of Url is unspecified if this return value is leaked without being dropped.

pub fn set_path(&mut self, path: &str)

Change this URL’s path.

Examples

use url::Url;

let mut url = Url::parse("https://example.com")?;
url.set_path("api/comments");
assert_eq!(url.as_str(), "https://example.com/api/comments");
assert_eq!(url.path(), "/api/comments");

let mut url = Url::parse("https://example.com/api")?;
url.set_path("data/report.csv");
assert_eq!(url.as_str(), "https://example.com/data/report.csv");
assert_eq!(url.path(), "/data/report.csv");

pub fn path_segments_mut(&mut self) -> Result<PathSegmentsMut<'_>, ()>

Return an object with methods to manipulate this URL’s path segments.

Return Err(()) if this URL is cannot-be-a-base.

pub fn set_port(&mut self, port: Option<u16>) -> Result<(), ()>

Change this URL’s port number.

Note that default port numbers are not reflected in the serialization.

If this URL is cannot-be-a-base, does not have a host, or has the file scheme; do nothing and return Err.

Examples

use url::Url;

let mut url = Url::parse("ssh://example.net:2048/")?;

url.set_port(Some(4096)).map_err(|_| "cannot be base")?;
assert_eq!(url.as_str(), "ssh://example.net:4096/");

url.set_port(None).map_err(|_| "cannot be base")?;
assert_eq!(url.as_str(), "ssh://example.net/");

Known default port numbers are not reflected:

use url::Url;

let mut url = Url::parse("https://example.org/")?;

url.set_port(Some(443)).map_err(|_| "cannot be base")?;
assert!(url.port().is_none());

Cannot set port for cannot-be-a-base URLs:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;

let result = url.set_port(Some(80));
assert!(result.is_err());

let result = url.set_port(None);
assert!(result.is_err());

pub fn set_host(&mut self, host: Option<&str>) -> Result<(), ParseError>

Change this URL’s host.

Removing the host (calling this with None) will also remove any username, password, and port number.

Examples

Change host:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_host(Some("rust-lang.org"));
assert!(result.is_ok());
assert_eq!(url.as_str(), "https://rust-lang.org/");

Remove host:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_host(None);
assert!(result.is_ok());
assert_eq!(url.as_str(), "foo:/");

Cannot remove host for 'special' schemes (e.g. http):

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_host(None);
assert!(result.is_err());
assert_eq!(url.as_str(), "https://example.net/");

Cannot change or remove host for cannot-be-a-base URLs:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;

let result = url.set_host(Some("rust-lang.org"));
assert!(result.is_err());
assert_eq!(url.as_str(), "mailto:rms@example.net");

let result = url.set_host(None);
assert!(result.is_err());
assert_eq!(url.as_str(), "mailto:rms@example.net");

Errors

If this URL is cannot-be-a-base or there is an error parsing the given host, a ParseError variant will be returned.

pub fn set_ip_host(&mut self, address: IpAddr) -> Result<(), ()>

Change this URL’s host to the given IP address.

If this URL is cannot-be-a-base, do nothing and return Err.

Compared to Url::set_host, this skips the host parser.

Examples

use url::{Url, ParseError};

let mut url = Url::parse("http://example.com")?;
url.set_ip_host("127.0.0.1".parse().unwrap());
assert_eq!(url.host_str(), Some("127.0.0.1"));
assert_eq!(url.as_str(), "http://127.0.0.1/");

Cannot change URL's from mailto(cannot-be-base) to ip:

use url::{Url, ParseError};

let mut url = Url::parse("mailto:rms@example.com")?;
let result = url.set_ip_host("127.0.0.1".parse().unwrap());

assert_eq!(url.as_str(), "mailto:rms@example.com");
assert!(result.is_err());

pub fn set_password(&mut self, password: Option<&str>) -> Result<(), ()>

Change this URL’s password.

If this URL is cannot-be-a-base or does not have a host, do nothing and return Err.

Examples

use url::{Url, ParseError};

let mut url = Url::parse("mailto:rmz@example.com")?;
let result = url.set_password(Some("secret_password"));
assert!(result.is_err());

let mut url = Url::parse("ftp://user1:secret1@example.com")?;
let result = url.set_password(Some("secret_password"));
assert_eq!(url.password(), Some("secret_password"));

let mut url = Url::parse("ftp://user2:@example.com")?;
let result = url.set_password(Some("secret2"));
assert!(result.is_ok());
assert_eq!(url.password(), Some("secret2"));

pub fn set_username(&mut self, username: &str) -> Result<(), ()>

Change this URL’s username.

If this URL is cannot-be-a-base or does not have a host, do nothing and return Err.

Examples

Cannot setup username from mailto(cannot-be-base)

use url::{Url, ParseError};

let mut url = Url::parse("mailto:rmz@example.com")?;
let result = url.set_username("user1");
assert_eq!(url.as_str(), "mailto:rmz@example.com");
assert!(result.is_err());

Setup username to user1

use url::{Url, ParseError};

let mut url = Url::parse("ftp://:secre1@example.com/")?;
let result = url.set_username("user1");
assert!(result.is_ok());
assert_eq!(url.username(), "user1");
assert_eq!(url.as_str(), "ftp://user1:secre1@example.com/");

pub fn set_scheme(&mut self, scheme: &str) -> Result<(), ()>

Change this URL’s scheme.

Do nothing and return Err if:

• The new scheme is not in [a-zA-Z][a-zA-Z0-9+.-]+
• This URL is cannot-be-a-base and the new scheme is one of http, https, ws, wss, ftp, or gopher

Examples

Change the URL’s scheme from https to foo:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_scheme("http");
assert_eq!(url.as_str(), "http://example.net/");
assert!(result.is_ok());

Change the URL’s scheme from foo to bar:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_scheme("bar");
assert_eq!(url.as_str(), "bar://example.net");
assert!(result.is_ok());

Cannot change URL’s scheme from https to foõ:

use url::Url;

let mut url = Url::parse("https://example.net")?;
let result = url.set_scheme("foõ");
assert_eq!(url.as_str(), "https://example.net/");
assert!(result.is_err());

Cannot change URL’s scheme from mailto (cannot-be-a-base) to https:

use url::Url;

let mut url = Url::parse("mailto:rms@example.net")?;
let result = url.set_scheme("https");
assert_eq!(url.as_str(), "mailto:rms@example.net");
assert!(result.is_err());

Cannot change the URL’s scheme from foo to https:

use url::Url;

let mut url = Url::parse("foo://example.net")?;
let result = url.set_scheme("https");
assert_eq!(url.as_str(), "foo://example.net");
assert!(result.is_err());

Cannot change the URL’s scheme from http to foo:

use url::Url;

let mut url = Url::parse("http://example.net")?;
let result = url.set_scheme("foo");
assert_eq!(url.as_str(), "http://example.net/");
assert!(result.is_err());

pub fn serialize_internal<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where
    S: Serializer, 

Serialize with Serde using the internal representation of the Url struct.

The corresponding deserialize_internal method sacrifices some invariant-checking for speed, compared to the Deserialize trait impl.

This method is only available if the serde Cargo feature is enabled.

pub fn to_file_path(&self) -> Result<PathBuf, ()>

Assuming the URL is in the file scheme or similar, convert its path to an absolute std::path::Path.

Note: This does not actually check the URL’s scheme, and may give nonsensical results for other schemes. It is the user’s responsibility to check the URL’s scheme before calling this.

let path = url.to_file_path();

Returns Err if the host is neither empty nor "localhost" (except on Windows, where file: URLs may have a non-local host), or if Path::new_opt() returns None. (That is, if the percent-decoded path contains a NUL byte or, for a Windows path, is not UTF-8.)
