Struct Params

Source
pub struct Params<'k, 'v> { /* private fields */ }
Expand description

A list of parameters returned by a route match.

let matched = router.at("/users/1")?;

// you can iterate through the keys and values
for (key, value) in matched.params.iter() {
    println!("key: {}, value: {}", key, value);
}

// or get a specific value by key
let id = matched.params.get("id");
assert_eq!(id, Some("1"));
