Fast WHATWG URL Specification compliant URL parser for Rust. Well-tested and widely used by Node.js since Node 18.
The Ada library passes the full range of tests from the specification, across a wide range of platforms (e.g., Windows, Linux, macOS). It fully supports the relevant Unicode Technical Standard.
See here for a usage example.
You can run it locally with cargo run --example simple.
Feel free to adjust it for exploring this crate further.
std: Functionalities that require std.
This feature is enabled by default, set no-default-features to true if you want no-std.
serde: Allow Url to work with serde. This feature is disabled by default. Enabling this feature without std would provide you only Serialize.
Enabling this feature and std would provide you both Serialize and Deserialize.
libcpp: Build ada-url with libc++. This feature is disabled by default.
Enabling this feature without libc++ installed would cause compile error.
Ada is fast. The benchmark below shows 3.49 times faster URL parsing compared to url

Url implements the following traits.
| Trait(s) | Description |
|---|---|
Display |
Provides to_string and allows for the value to be used in format! macros (e.g. println!). |
Debug |
Allows debugger output in format macros, ({:?} syntax) |
PartialEq, Eq |
Allows for comparison, url1 == url2, url1.eq(url2) |
PartialOrd, Ord |
Allows for ordering url1 < url2, done so alphabetically. This is also allows Url to be used as a key in a BTreeMap |
Hash |
Makes it so that Url can be hashed based on the string representation. This is important so that Url can be used as a key in a HashMap |
FromStr |
Allows for use with str's parse method |
TryFrom<String>, TryFrom<&str> |
Provides try_into methods for String and &str |
Borrow<str>, Borrow<[u8]> |
Used in some crates so that the Url can be used as a key. |
Deref<Target=str> |
Allows for &Url to dereference as a &str. Also provides a number of string methods |
AsRef<[u8]>, AsRef<str> |
Used to do a cheap reference-to-reference conversion. |
Send |
Used to declare that the type can be transferred across thread boundaries. |
Sync |
Used to declare that the type is thread-safe. |
The justfile contains commands (called "recipes") that can be executed by just for convenience.
