Methods

fn build() -> LinkBuilder

Methods from Deref<Target = Uri>

fn path_and_query(&self) -> Option<&PathAndQuery>

Returns the path & query components of the Uri

fn path(&self) -> &str

Get the path of this Uri.

Both relative and absolute URIs contain a path component, though it might be the empty string. The path component is case sensitive.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
                                       |--------|
                                            |
                                          path

If the URI is * then the path component is equal to *.

Examples

A relative URI

let uri: Uri = "/hello/world".parse().unwrap();

assert_eq!(uri.path(), "/hello/world");

An absolute URI

let uri: Uri = "http://example.org/hello/world".parse().unwrap();

assert_eq!(uri.path(), "/hello/world");

fn scheme(&self) -> Option<&str>

Get the scheme of this Uri.

The URI scheme refers to a specification for assigning identifiers within that scheme. Only absolute URIs contain a scheme component, but not all absolute URIs will contain a scheme component. Although scheme names are case-insensitive, the canonical form is lowercase.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
|-|
 |
scheme

Examples

Absolute URI

let uri: Uri = "http://example.org/hello/world".parse().unwrap();

assert_eq!(uri.scheme(), Some("http"));

Relative URI

let uri: Uri = "/hello/world".parse().unwrap();

assert!(uri.scheme().is_none());

fn authority_part(&self) -> Option<&Authority>

Get the authority of this Uri.

The authority is a hierarchical element for naming authority such that the remainder of the URI is delegated to that authority. For HTTP, the authority consists of the host and port. The host portion of the authority is case-insensitive.

The authority also includes a username:password component, however the use of this is deprecated and should be avoided.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
      |-------------------------------|
                    |
                authority

This function will be renamed to authority in the next semver release.

Examples

Absolute URI

let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();

assert_eq!(uri.authority_part().map(|a| a.as_str()), Some("example.org:80"));

Relative URI

let uri: Uri = "/hello/world".parse().unwrap();

assert!(uri.authority_part().is_none());

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

Get the host of this Uri.

The host subcomponent of authority is identified by an IP literal encapsulated within square brackets, an IPv4 address in dotted- decimal form, or a registered name. The host subcomponent is case-insensitive.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
                        |---------|
                             |
                            host

Examples

Absolute URI

let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();

assert_eq!(uri.host(), Some("example.org"));

Relative URI

let uri: Uri = "/hello/world".parse().unwrap();

assert!(uri.host().is_none());

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

Get the port of this Uri.

The port subcomponent of authority is designated by an optional port number in decimal following the host and delimited from it by a single colon (":") character. A value is only returned if one is specified in the URI string, i.e., default port values are not returned.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
                                    |-|
                                     |
                                    port

Examples

Absolute URI with port

let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();

assert_eq!(uri.port(), Some(80));

Absolute URI without port

let uri: Uri = "http://example.org/hello/world".parse().unwrap();

assert!(uri.port().is_none());

Relative URI

let uri: Uri = "/hello/world".parse().unwrap();

assert!(uri.port().is_none());

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

Get the query string of this Uri, starting after the ?.

The query component contains non-hierarchical data that, along with data in the path component, serves to identify a resource within the scope of the URI's scheme and naming authority (if any). The query component is indicated by the first question mark ("?") character and terminated by a number sign ("#") character or by the end of the URI.

abc://username:password@example.com:123/path/data?key=value&key2=value2#fragid1
                                                  |-------------------|
                                                            |
                                                          query

Examples

Absolute URI

let uri: Uri = "http://example.org/hello/world?key=value".parse().unwrap();

assert_eq!(uri.query(), Some("key=value"));

Relative URI with a query string component

let uri: Uri = "/hello/world?key=value&foo=bar".parse().unwrap();

assert_eq!(uri.query(), Some("key=value&foo=bar"));

Relative URI without a query string component

let uri: Uri = "/hello/world".parse().unwrap();

assert!(uri.query().is_none());
