| |
| rust-url is an implementation of the [URL Standard](http://url.spec.whatwg.org/) |
| for the [Rust](http://rust-lang.org/) programming language. |
| |
| |
| # URL parsing and data structures |
| |
| First, URL parsing may fail for various reasons and therefore returns a `Result`. |
| |
| ``` |
| use url::{Url, ParseError}; |
| |
| assert!(Url::parse("http://[:::1]") == Err(ParseError::InvalidIpv6Address)) |
| ``` |
| |
| Let’s parse a valid URL and look at its components. |
| |
| ``` |
| use url::{Url, Host, Position}; |
| # use url::ParseError; |
| # fn run() -> Result<(), ParseError> { |
| let issue_list_url = Url::parse( |
| "https://github.com/rust-lang/rust/issues?labels=E-easy&state=open" |
| )?; |
| |
| |
| assert!(issue_list_url.scheme() == "https"); |
| assert!(issue_list_url.username() == ""); |
| assert!(issue_list_url.password() == None); |
| assert!(issue_list_url.host_str() == Some("github.com")); |
| assert!(issue_list_url.host() == Some(Host::Domain("github.com"))); |
| assert!(issue_list_url.port() == None); |
| assert!(issue_list_url.path() == "/rust-lang/rust/issues"); |
| assert!(issue_list_url.path_segments().map(|c| c.collect::<Vec<_>>()) == |
| Some(vec!["rust-lang", "rust", "issues"])); |
| assert!(issue_list_url.query() == Some("labels=E-easy&state=open")); |
| assert!(&issue_list_url[Position::BeforePath..] == "/rust-lang/rust/issues?labels=E-easy&state=open"); |
| assert!(issue_list_url.fragment() == None); |
| assert!(!issue_list_url.cannot_be_a_base()); |
| # Ok(()) |
| # } |
| # run().unwrap(); |
| ``` |
| |
| Some URLs are said to be *cannot-be-a-base*: |
| they don’t have a username, password, host, or port, |
| and their "path" is an arbitrary string rather than slash-separated segments: |
| |
| ``` |
| use url::Url; |
| # use url::ParseError; |
| |
| # fn run() -> Result<(), ParseError> { |
| let data_url = Url::parse("data:text/plain,Hello?World#")?; |
| |
| assert!(data_url.cannot_be_a_base()); |
| assert!(data_url.scheme() == "data"); |
| assert!(data_url.path() == "text/plain,Hello"); |
| assert!(data_url.path_segments().is_none()); |
| assert!(data_url.query() == Some("World")); |
| assert!(data_url.fragment() == Some("")); |
| # Ok(()) |
| # } |
| # run().unwrap(); |
| ``` |
| |
| ## Serde |
| |
| Enable the `serde` feature to include `Deserialize` and `Serialize` implementations for `url::Url`. |
| |
| # Base URL |
| |
| Many contexts allow URL *references* that can be relative to a *base URL*: |
| |
| ```html |
| <link rel="stylesheet" href="../main.css"> |
| ``` |
| |
| Since parsed URLs are absolute, giving a base is required for parsing relative URLs: |
| |
| ``` |
| use url::{Url, ParseError}; |
| |
| assert!(Url::parse("../main.css") == Err(ParseError::RelativeUrlWithoutBase)) |
| ``` |
| |
| Use the `join` method on an `Url` to use it as a base URL: |
| |
| ``` |
| use url::Url; |
| # use url::ParseError; |
| |
| # fn run() -> Result<(), ParseError> { |
| let this_document = Url::parse("http://servo.github.io/rust-url/url/index.html")?; |
| let css_url = this_document.join("../main.css")?; |
| assert_eq!(css_url.as_str(), "http://servo.github.io/rust-url/main.css"); |
| # Ok(()) |
| # } |
| # run().unwrap(); |
| ``` |
| |
| # Feature: `serde` |
| |
| If you enable the `serde` feature, [`Url`](struct.Url.html) will implement |
| [`serde::Serialize`](https://docs.rs/serde/1/serde/trait.Serialize.html) and |
| [`serde::Deserialize`](https://docs.rs/serde/1/serde/trait.Deserialize.html). |
| See [serde documentation](https://serde.rs) for more information. |
| |
| ```toml |
| url = { version = "2", features = ["serde"] } |
| ``` |
