#62290)Expand description
An async-aware version of the FnMut
trait.
All async fn
and functions returning futures implement this trait.

)
type CallRefFuture<'a>: Future<Output = Self::Output> where Self: 'a
async_fn_traits
)Future returned by AsyncFnMut::async_call_mut
and AsyncFn::async_call
.
Required Methods§

extern "rust-call" fn async_call_mut( &mut self, args: Args, ) -> Self::CallRefFuture<'_>
async_fn_traits
)Call the AsyncFnMut
, returning a future which may borrow from the called closure.
