Struct Callback

pub struct Callback<In, Out = ()>(/* private fields */)
where
    In: 'static,
    Out: 'static;

Expand description

A callback type that is Send + Sync.

§Example

let _: Callback<()> = Callback::new(|_| {});
let _: Callback<(i32, i32)> = (|_x: i32, _y: i32| {}).into();
let cb: Callback<i32, String> = Callback::new(|x: i32| x.to_string());
assert_eq!(cb.run(42), "42".to_string());
