Trait AsyncFnOnce 

pub trait AsyncFnOnce<Args> {
    type Output;
    type Future: Future<Output = Self::Output> + Send;

    // Required method
    fn call_once(self, _: Args) -> Self::Future;
}

Required Associated Types

type Output

type Future: Future<Output = Self::Output> + Send

Required Methods

fn call_once(self, _: Args) -> Self::Future

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<Func, Args> AsyncFnOnce<Args> for Func

where Func: FnOnce<Args>, Func::Output: Future + Send,

type Output = <<Func as FnOnce<Args>>::Output as Future>::Output

type Future = <Func as FnOnce<Args>>::Output
