🔬This is a nightly-only experimental API. (
async_fn_traits
)Expand description
An async-aware version of the Fn
trait.
All async fn
and functions returning futures implement this trait.
Required Associated Types§
sourcetype CallFuture<'a>: Future<Output = Self::Output>
where
Self: 'a
type CallFuture<'a>: Future<Output = Self::Output> where Self: 'a
🔬This is a nightly-only experimental API. (
async_fn_traits
)Future returned by AsyncFn::async_call
.
Required Methods§
sourceextern "rust-call" fn async_call(
&self,
args: Args
) -> Self::CallFuture<'_>
extern "rust-call" fn async_call( &self, args: Args ) -> Self::CallFuture<'_>
🔬This is a nightly-only experimental API. (
async_fn_traits
)Call the AsyncFn
, returning a future which may borrow from the called closure.
Object Safety§
This trait is not object safe.
