[−][src]Function rweb::filters::any::any
pub fn any() -> impl Filter + Copy
A filter that matches any route.
This can be a useful building block to build new filters from,
since Filter
is otherwise a sealed trait.
Example
use warp::Filter; let route = warp::any() .map(|| { "I always return this string!" });
This could allow creating a single impl Filter
returning a specific
reply, that can then be used as the end of several different filter
chains.
Another use case is turning some clone-able resource into a Filter
,
thus allowing to easily and
it together with others.
use std::sync::Arc; use warp::Filter; let state = Arc::new(vec![33, 41]); let with_state = warp::any().map(move || state.clone()); // Now we could `and` with any other filter: let route = warp::path::param() .and(with_state) .map(|param_id: u32, db: Arc<Vec<u32>>| { db.contains(¶m_id) });
