Struct URI

Source

pub struct URI<'uri> { /* private fields */ }

Expand description

A Uniform Resource Identifier (URI) as defined in RFC3986.

A URI is a URI reference, one with a scheme.

Implementations§

Source §

impl<'uri> URI<'uri>

Source

pub fn as_uri_reference(&self) -> &URIReference<'uri>

Source

pub fn authority(&self) -> Option<&Authority<'uri>>

Returns the authority, if present, of the URI.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com:80/my/path").unwrap();
assert_eq!(uri.authority().unwrap().to_string(), "example.com:80");

Source

pub fn builder<'new_uri>() -> URIBuilder<'new_uri>

Constructs a default builder for a URI.

This provides an alternative means of constructing a URI besides parsing and URI::from_parts.

§Examples

use std::convert::TryFrom;

use uriparse::{Authority, Path, Scheme, URI};

let uri = URI::builder()
    .with_scheme(Scheme::HTTP)
    .with_authority(Some(Authority::try_from("example.com").unwrap()))
    .with_path(Path::try_from("/my/path").unwrap())
    .build()
    .unwrap();
assert_eq!(uri.to_string(), "http://example.com/my/path");

Source

pub fn can_be_a_base(&self) -> bool

Returns whether the URI can act as a base URI.

A URI can be a base if it is absolute (i.e. it has no fragment component).

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com/my/path").unwrap();
assert!(uri.can_be_a_base());

let uri = URI::try_from("ftp://127.0.0.1#fragment").unwrap();
assert!(!uri.can_be_a_base());

Source

pub fn from_parts<'new_uri, TScheme, TAuthority, TPath, TQuery, TFragment, TSchemeError, TAuthorityError, TPathError, TQueryError, TFragmentError>( scheme: TScheme, authority: Option<TAuthority>, path: TPath, query: Option<TQuery>, fragment: Option<TFragment>, ) -> Result<URI<'new_uri>, URIError>
where Scheme<'new_uri>: TryFrom<TScheme, Error = TSchemeError>, Authority<'new_uri>: TryFrom<TAuthority, Error = TAuthorityError>, Path<'new_uri>: TryFrom<TPath, Error = TPathError>, Query<'new_uri>: TryFrom<TQuery, Error = TQueryError>, Fragment<'new_uri>: TryFrom<TFragment, Error = TFragmentError>, URIReferenceError: From<TSchemeError> + From<TAuthorityError> + From<TPathError> + From<TQueryError> + From<TFragmentError>,

Constructs a new URI from the individual parts: scheme, authority, path, query, and fragment.

The lifetime used by the resulting value will be the lifetime of the part that is most restricted in scope.

§Examples

use std::convert::TryFrom;

use uriparse::{Fragment, URI};

let uri = URI::from_parts(
    "http",
    Some("example.com"),
    "",
    Some("query"),
    None::<Fragment>
).unwrap();
assert_eq!(uri.to_string(), "http://example.com/?query");

Source

pub fn fragment(&self) -> Option<&Fragment<'uri>>

Returns the fragment, if present, of the URI.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com#fragment").unwrap();
assert_eq!(uri.fragment().unwrap(), "fragment");

Source

pub fn has_authority(&self) -> bool

Returns whether the URI has an authority component.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com").unwrap();

assert!(!uri.has_authority());

Source

pub fn has_fragment(&self) -> bool

Returns whether the URI has a fragment component.

let uri = URI::try_from("http://example.com#test").unwrap();
assert!(uri.has_fragment());

let uri = URI::try_from("http://example.com").unwrap();
assert!(!uri.has_fragment());

Source

pub fn has_password(&self) -> bool

Returns whether the URI has a password component.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://user:pass@127.0.0.1").unwrap();
assert!(uri.has_password());

let uri = URI::try_from("http://user@127.0.0.1").unwrap();
assert!(!uri.has_password());

Source

pub fn has_port(&self) -> bool

Returns whether the URI has a port.

§Examples

use uriparse::URI;

let uri = URI::try_from("http://127.0.0.1:8080").unwrap();
assert!(uri.has_port());

let uri = URI::try_from("http://127.0.0.1").unwrap();
assert!(!uri.has_port());

Source

pub fn has_query(&self) -> bool

Returns whether the URI has a query component.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com/my/path?my=query").unwrap();
assert!(uri.has_query());

let uri = URI::try_from("http://example.com/my/path").unwrap();
assert!(!uri.has_query());

Source

pub fn has_username(&self) -> bool

Returns whether the URI has a username component.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://username@example.com").unwrap();
assert!(uri.has_username());

let uri = URI::try_from("http://example.com").unwrap();
assert!(!uri.has_username());

Source

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

Returns the host, if present, of the URI.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://username@example.com").unwrap();
assert_eq!(uri.host().unwrap().to_string(), "example.com");

Source

pub fn into_base_uri(self) -> URI<'uri>

Converts the URI into a base URI (i.e. the fragment component is removed).

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com#fragment").unwrap();
assert_eq!(uri.to_string(), "http://example.com/#fragment");
let uri = uri.into_base_uri();
assert_eq!(uri.to_string(), "http://example.com/");

Source

pub fn into_builder(self) -> URIBuilder<'uri>

Consumes the URI and converts it into a builder with the same values.

§Examples

use std::convert::TryFrom;

use uriparse::{Fragment, Query, URI};

let uri = URI::try_from("http://example.com/path?query#fragment").unwrap();
let mut builder = uri.into_builder();
builder.query(None::<Query>).fragment(None::<Fragment>);
let uri = builder.build().unwrap();
assert_eq!(uri.to_string(), "http://example.com/path");

Source

pub fn into_owned(self) -> URI<'static>

Converts the URI into an owned copy.

If you construct the URI from a source with a non-static lifetime, you may run into lifetime problems due to the way the struct is designed. Calling this function will ensure that the returned value has a static lifetime.

This is different from just cloning. Cloning the URI will just copy the references, and thus the lifetime will remain the same.

Source

pub fn into_parts( self, ) -> (Scheme<'uri>, Option<Authority<'uri>>, Path<'uri>, Option<Query<'uri>>, Option<Fragment<'uri>>)

Consumes the URI and returns its parts: scheme, authority, path, query, and fragment.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from(
    "http://username:password@example.com:80/my/path?my=query#fragment",
).unwrap();
let (scheme, authority, path, query, fragment) = uri.into_parts();

assert_eq!(scheme, "http");
assert_eq!(authority.unwrap().to_string(), "username:password@example.com:80");
assert_eq!(path, "/my/path");
assert_eq!(query.unwrap(), "my=query");
assert_eq!(fragment.unwrap(), "fragment");

Source

pub fn is_normalized(&self) -> bool

Returns whether the URI is normalized.

A normalized URI will have all of its components normalized.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let uri = URI::try_from("http://example.com/?a=b").unwrap();
assert!(uri.is_normalized());

let mut uri = URI::try_from("http://EXAMPLE.com/?a=b").unwrap();
assert!(!uri.is_normalized());
uri.normalize();
assert!(uri.is_normalized());

Source

    path.push("path").unwrap();
    path
});
assert_eq!(uri.to_string(), "http://example.com/test/path");

Source

pub fn resolve(&self, reference: &'uri URIReference<'uri>) -> URI<'uri>

Creates a new URI which is created by resolving the given reference against this URI.

The algorithm used for resolving the reference is described in [RFC3986, Section 5.2.2].

Source

pub fn scheme(&self) -> &Scheme<'uri>

Returns the scheme of the URI.

§Examples

use std::convert::TryFrom;

Source

pub fn set_authority<TAuthority, TAuthorityError>( &mut self, authority: Option<TAuthority>, ) -> Result<Option<&Authority<'uri>>, URIError>
where Authority<'uri>: TryFrom<TAuthority, Error = TAuthorityError>, URIReferenceError: From<TAuthorityError>,

Sets the authority of the URI.

An error will be returned if the conversion to an Authority fails.

The existing path will be set to absolute (i.e. starts with a '/').

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let mut uri = URI::try_from("http://example.com").unwrap();
uri.set_authority(Some("user@example.com:80"));

pub fn set_fragment<TFragment, TFragmentError>( &mut self, fragment: Option<TFragment>, ) -> Result<Option<&Fragment<'uri>>, URIError>
where Fragment<'uri>: TryFrom<TFragment, Error = TFragmentError>, URIReferenceError: From<TFragmentError>,

Sets the fragment of the URI.

An error will be returned if the conversion to a Fragment fails.

§Examples

use std::convert::TryFrom;

uri.set_fragment(Some("fragment"));
assert_eq!(uri.to_string(), "http://example.com/#fragment");

Source

pub fn set_path<TPath, TPathError>( &mut self, path: TPath, ) -> Result<&Path<'uri>, URIError>
where Path<'uri>: TryFrom<TPath, Error = TPathError>, URIReferenceError: From<TPathError>,

Sets the path of the URI.

An error will be returned in one of two cases:

The conversion to Path failed.
The path was set to a value that resulted in an invalid URI.

Regardless of whether the given path was set as absolute or relative, if the URI reference currently has an authority, the path will be forced to be absolute.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let mut uri = URI::try_from("http://example.com").unwrap();
uri.set_path("my/path");

Sets the query of the URI.

An error will be returned if the conversion to a Query fails.

§Examples

use std::convert::TryFrom;

use uriparse::URI;

let mut uri = URI::try_from("http://example.com").unwrap();
uri.set_query(Some("myquery"));
assert_eq!(uri.to_string(), "http://example.com/?myquery");

use uriparse::URI;

let mut uri = URI::try_from("http://example.com").unwrap();
uri.set_scheme("https");
assert_eq!(uri.to_string(), "https://example.com/");
