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.

(De)serialization

Authority is both Serialize and Deserialize:

use serde::{Serialize, Deserialize};
use rocket::http::uri::Authority;

#[derive(Deserialize, Serialize)]
struct UriOwned {
    uri: Authority<'static>,
}

#[derive(Deserialize, Serialize)]
struct UriBorrowed<'a> {
    uri: Authority<'a>,
}

Implementations§

source§

impl<'a> Authority<'a>

source

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("https://rocket.rs").expect_err("invalid authority");

// Prefer to use `uri!()` when the input is statically known:
let uri = uri!("user:pass@host");
assert_eq!(uri.user_info(), Some("user:pass"));
assert_eq!(uri.host(), "host");
assert_eq!(uri.port(), None);
source

pub fn parse_owned(string: String) -> Result<Authority<'static>, Error<'static>>

Parses the string string into an Authority. Parsing never allocates on success. May allocate on error.

This method should be used instead of Authority::parse() when the source URI is already a String. Returns an Error if string is not a valid authority URI.

Example
use rocket::http::uri::Authority;

let source = format!("rocket.rs:8000");
let uri = Authority::parse_owned(source).expect("valid URI");
assert!(uri.user_info().is_none());
assert_eq!(uri.host(), "rocket.rs");
assert_eq!(uri.port(), Some(8000));
source

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

Returns the user info part of the authority URI, if there is one.

Example
let uri = uri!("username:password@host");
assert_eq!(uri.user_info(), Some("username:password"));
source

pub fn host(&self) -> &str

Returns the host part of the authority URI.

Example
let uri = uri!("domain.com:123");
assert_eq!(uri.host(), "domain.com");

let uri = uri!("username:password@host:123");
assert_eq!(uri.host(), "host");

let uri = uri!("username:password@[1::2]:123");
assert_eq!(uri.host(), "[1::2]");
source

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

Returns the port part of the authority URI, if there is one.

Example
// With a port.
let uri = uri!("username:password@host:123");
assert_eq!(uri.port(), Some(123));

let uri = uri!("domain.com:8181");
assert_eq!(uri.port(), Some(8181));

// Without a port.
let uri = uri!("username:password@host");
assert_eq!(uri.port(), None);
