Function warp::filters::path::tail

pub fn tail() -> impl Filter<Extract = (Tail,), Error = Infallible> + Copy

Extract the unmatched tail of the path.

This will return a Tail, which allows access to the rest of the path that previous filters have not already matched.

Example

use warp::Filter;

let route = warp::path("foo")
    .and(warp::path::tail())
    .map(|tail| {
        // GET /foo/bar/baz would return "bar/baz".
        format!("The tail after foo is {:?}", tail)
    });
