Trait SinkExt 

pub(crate) trait SinkExt<T>: Sink<T> {
    // Provided method
    fn poll_ready_unpin_bool(

Provided Methods

fn poll_ready_unpin_bool( &mut self, cx: &mut Context<'_>, ) -> Result<bool, Self::Error>

where Self: Unpin,

Calls futures::Sink::poll_ready but requires Unpin and returns bool

Various gnarly places in the circuit reactor find this convenient.

TODO #1397 (circuit reactor) probably remove this when the circuit reactor is rewritten.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
