Trait AsyncFnMut

source
pub trait AsyncFnMut<Args>: AsyncFnOnce<Args>
where Args: Tuple,
{ type CallRefFuture<'a>: Future<Output = Self::Output> where Self: 'a; // Required method extern "rust-call" fn async_call_mut( &mut self, args: Args, ) -> Self::CallRefFuture<'_>; }

Expand description

An async-aware version of the FnMut trait.

All async fn and functions returning futures implement this trait.

Required Associated Types§

source

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

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

Required Methods§

source

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

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