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"] }
```
# Feature: `debugger_visualizer`
If you enable the `debugger_visualizer` feature, the `url` crate will include
a [natvis file](https://docs.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects)
for [Visual Studio](https://www.visualstudio.com/) that allows you to view
[`Url`](struct.Url.html) objects in the debugger.
This feature requires Rust 1.71 or later.
```toml
url = { version = "2", features = ["debugger_visualizer"] }
```

Getters and setters for URL components implemented per <https://url.spec.whatwg.org/#api>
Unless you need to be interoperable with web browsers,
you probably want to use `Url` method instead. |
