Struct rocket_http::uri::Authority
source · [−]pub struct Authority<'a> { /* private fields */ }
Expand description
A URI with an authority only: user:pass@host:8000
.
Structure
The following diagram illustrates the syntactic structure of an authority URI:
username:password@some.host:8088
|---------------| |-------| |--|
user info host port
Only the host part of the URI is required.
Implementations
sourceimpl<'a> Authority<'a>
impl<'a> Authority<'a>
sourcepub fn parse(string: &'a str) -> Result<Authority<'a>, Error<'a>>
pub fn parse(string: &'a str) -> Result<Authority<'a>, Error<'a>>
Parses the string string
into an Authority
. Parsing will never
allocate. Returns an Error
if string
is not a valid authority URI.
Example
use rocket::http::uri::Authority;
// Parse a valid authority URI.
let uri = Authority::parse("user:pass@host").expect("valid URI");
assert_eq!(uri.user_info(), Some("user:pass"));
assert_eq!(uri.host(), "host");
assert_eq!(uri.port(), None);
// Invalid authority URIs fail to parse.
Authority::parse("http://google.com").expect_err("invalid authority");
sourcepub fn user_info(&self) -> Option<&str>
pub fn user_info(&self) -> Option<&str>
Returns the user info part of the authority URI, if there is one.
Example
use rocket::http::uri::Authority;
let uri = Authority::parse("username:password@host").unwrap();
assert_eq!(uri.user_info(), Some("username:password"));
sourcepub fn host(&self) -> &str
pub fn host(&self) -> &str
Returns the host part of the authority URI.
If the host was provided in brackets (such as for IPv6 addresses), the brackets will not be part of the returned string.
Example
use rocket::http::uri::Authority;
let uri = Authority::parse("domain.com:123").unwrap();
assert_eq!(uri.host(), "domain.com");
let uri = Authority::parse("username:password@host:123").unwrap();
assert_eq!(uri.host(), "host");
let uri = Authority::parse("username:password@[1::2]:123").unwrap();
assert_eq!(uri.host(), "1::2");
sourcepub fn port(&self) -> Option<u16>
pub fn port(&self) -> Option<u16>
Returns the port part of the authority URI, if there is one.
Example
use rocket::http::uri::Authority;
// With a port.
let uri = Authority::parse("username:password@host:123").unwrap();
assert_eq!(uri.port(), Some(123));
let uri = Authority::parse("domain.com:8181").unwrap();
assert_eq!(uri.port(), Some(8181));
// Without a port.
let uri = Authority::parse("username:password@host").unwrap();
assert_eq!(uri.port(), None);
