Required Methods§

Source

fn is_some_and_async<F, Fut>(self, f: F) -> impl Future<Output = bool>
where F: FnOnce(T) -> Fut, Fut: Future<Output = bool>,

Source

fn is_none_or_async<F, Fut>(self, f: F) -> impl Future<Output = bool>
where F: FnOnce(T) -> Fut, Fut: Future<Output = bool>,

Source

fn map_async<B, F, Fut>(self, f: F) -> impl Future<Output = Option<B>>
where F: FnOnce(T) -> Fut, Fut: Future<Output = B>,

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.
