Trait core::ops::AsyncFnMut

pub trait AsyncFnMut<Args: Tuple>: AsyncFnOnce<Args> {
    type CallMutFuture<'a>: Future<Output = Self::Output>
       where Self: 'a;

    // Required method
    extern "rust-call" fn async_call_mut(
        &mut self,
        args: Args
    ) -> Self::CallMutFuture<'_>;
}

🔬This is a nightly-only experimental API. (async_fn_traits)

An async-aware version of the FnMut trait.

All async fn and functions returning futures implement this trait.

Required Associated Types

type CallMutFuture<'a>: Future<Output = Self::Output> where Self: 'a

🔬This is a nightly-only experimental API. (async_fn_traits)

Future returned by AsyncFnMut::async_call_mut.

Required Methods

extern "rust-call" fn async_call_mut( &mut self, args: Args ) -> Self::CallMutFuture<'_>

🔬This is a nightly-only experimental API. (async_fn_traits)

Call the AsyncFnMut, returning a future which may borrow from the called closure.

Object Safety

This trait is not object safe.
