async_closure
)Expand description
An async-aware version of the FnMut
trait.
All async fn
and functions returning futures implement this trait.
Required Associated Types§
sourcetype CallRefFuture<'a>: Future<Output = Self::Output>
where
Self: 'a
🔬This is a nightly-only experimental API. (async_fn_traits
)
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§
sourceextern "rust-call" fn async_call_mut(
&mut self,
args: Args,
) -> Self::CallRefFuture<'_>
🔬This is a nightly-only experimental API. (async_fn_traits
)
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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
