Expand description
Extract a parameter from a path segment.
This will try to parse a value from the current request path
segment, and if successful, the value is returned as the Filter
’s
“extracted” value.
If the value could not be parsed, rejects with a 404 Not Found
.
Example
use warp::Filter;
let route = warp::path::param()
.map(|id: u32| {
format!("You asked for /{}", id)
});
