pub struct Uri {
scheme: Scheme,
authority: Authority,
path_and_query: PathAndQuery,
}
Expand description
The URI component of a request.
For HTTP 1, this is included as part of the request line. From Section 5.3, Request Target:
Once an inbound connection is obtained, the client sends an HTTP request message (Section 3) with a request-target derived from the target URI. There are four distinct formats for the request-target, depending on both the method being requested and whether the request is to a proxy.
request-target = origin-form / absolute-form / authority-form / asterisk-form
The URI is structured as follows:
abc://username:[email protected]:123/path/data?key=value&key2=value2#fragid1
|-| |-------------------------------||--------| |-------------------| |-----|
| | | | |
scheme authority path query fragment
For HTTP 2.0, the URI is encoded using pseudoheaders.
§Examples
use http::Uri;
let uri = "/foo/bar?baz".parse::<Uri>().unwrap();
assert_eq!(uri.path(), "/foo/bar");
assert_eq!(uri.query(), Some("baz"));
assert_eq!(uri.host(), None);
let uri = "https://www.rust-lang.org/install.html".parse::<Uri>().unwrap();
assert_eq!(uri.scheme_str(), Some("https"));
assert_eq!(uri.host(), Some("www.rust-lang.org"));
assert_eq!(uri.path(), "/install.html");

Implementations§
source§impl Uri
impl Uri
sourcepub fn builder() -> Builder
pub fn builder() -> Builder
Creates a new builder-style object to manufacture a Uri
.
This method returns an instance of Builder
which can be usd to
create a Uri
.
§Examples
use http::Uri;
let uri = Uri::builder()
.scheme("https")
.authority("hyper.rs")
.path_and_query("/")
.build()
.unwrap();
sourcepub fn from_parts(src: Parts) -> Result<Uri, InvalidUriParts>
pub fn from_parts(src: Parts) -> Result<Uri, InvalidUriParts>
Attempt to convert a Parts
into a Uri
.
§Examples
Relative URI
let mut parts = Parts::default();
parts.path_and_query = Some("/foo".parse().unwrap());
let uri = Uri::from_parts(parts).unwrap();
assert_eq!(uri.path(), "/foo");
assert!(uri.scheme().is_none());
assert!(uri.authority().is_none());
Absolute URI
let mut parts = Parts::default();
parts.scheme = Some("http".parse().unwrap());
parts.authority = Some("foo.com".parse().unwrap());
parts.path_and_query = Some("/foo".parse().unwrap());
let uri = Uri::from_parts(parts).unwrap();
assert_eq!(uri.scheme().unwrap().as_str(), "http");
assert_eq!(uri.authority().unwrap(), "foo.com");
assert_eq!(uri.path(), "/foo");
Attempt to convert a Bytes
buffer to a Uri
.
This will try to prevent a copy if the type passed is the type used internally, and will copy the data if it is not.
sourcepub fn from_static(src: &'static str) -> Uri
pub fn from_static(src: &'static str) -> Uri
Convert a Uri
from a static string.
This function will not perform any copying, however the string is checked to ensure that it is valid.
§Panics
This function panics if the argument is an invalid URI.
§Examples
let uri = Uri::from_static("http://example.com/foo");
assert_eq!(uri.host().unwrap(), "example.com");
assert_eq!(uri.path(), "/foo");
sourcepub fn into_parts(self) -> Parts
pub fn into_parts(self) -> Parts
Convert a Uri
into Parts
.
§Note
This is just an inherent method providing the same functionality as
let parts: Parts = uri.into()
§Examples
let uri: Uri = "/foo".parse().unwrap();
let parts = uri.into_parts();
assert_eq!(parts.path_and_query.unwrap(), "/foo");
assert!(parts.scheme.is_none());
assert!(parts.authority.is_none());
sourcepub fn path_and_query(&self) -> Option<&PathAndQuery>
pub fn path_and_query(&self) -> Option<&PathAndQuery>
Returns the path & query components of the Uri
sourcepub fn path(&self) -> &str
pub 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.

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");
sourcepub fn scheme(&self) -> Option<&Scheme>
pub fn scheme(&self) -> Option<&Scheme>
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.

scheme
§Examples
Absolute URI
use http::uri::{Scheme, Uri};
let uri: Uri = "http://example.org/hello/world".parse().unwrap();
assert_eq!(uri.scheme(), Some(&Scheme::HTTP));
Relative URI
let uri: Uri = "/hello/world".parse().unwrap();
assert!(uri.scheme().is_none());
sourcepub fn scheme_str(&self) -> Option<&str>
pub fn scheme_str(&self) -> Option<&str>
Get the scheme of this Uri
as a &str
.
§Example
let uri: Uri = "http://example.org/hello/world".parse().unwrap();
assert_eq!(uri.scheme_str(), Some("http"));
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.

authority
§Examples
Absolute URI
let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();
assert_eq!(uri.authority().map(|a| a.as_str()), Some("example.org:80"));
Relative URI
let uri: Uri = "/hello/world".parse().unwrap();
assert!(uri.authority().is_none());
sourcepub fn host(&self) -> Option<&str>
pub 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.

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());
sourcepub fn port(&self) -> Option<Port<&str>>
pub fn port(&self) -> Option<Port<&str>>
Get the port part of this Uri
.
The port subcomponent of authority is designated by an optional port
number following the host and delimited from it by a single colon (“:”)
character. It can be turned into a decimal port number with the as_u16
method or as a str
with the as_str
method.

port
§Examples
Absolute URI with port
let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();
let port = uri.port().unwrap();
assert_eq!(port.as_u16(), 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());
sourcepub fn port_u16(&self) -> Option<u16>
pub fn port_u16(&self) -> Option<u16>
Get the port of this Uri
as a u16
.
§Example
let uri: Uri = "http://example.org:80/hello/world".parse().unwrap();
assert_eq!(uri.port_u16(), Some(80));
sourcepub fn query(&self) -> Option<&str>
pub 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.

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());
