Trait wasmtime_environ::__core::ops::AsyncFn

pub trait AsyncFn<Args>: AsyncFnMut<Args>
where
    Args: Tuple,
{
    // Required method
    extern "rust-call" fn async_call(
        &self,
        args: Args,
    ) -> Self::CallRefFuture<'_>;
}

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

An async-aware version of the Fn trait.

All async fn and functions returning futures implement this trait.

Required Methods

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

🔬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.
