Trait for use with the demux_enum operator.

This trait is meant to be derived: #[derive(DemuxEnum)].

The derive will implement this such that Outputs can be any tuple where each item is a Sink that corresponds to each of the variants of the tuple, in alphabetic order.

Required Associated Types

type Error

The error type for pushing self into the Outputs Sinks.

Required Methods

fn poll_ready( outputs: &mut Outputs, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Call poll_ready on all Outputs.

fn start_send(self, outputs: &mut Outputs) -> Result<(), Self::Error>

Pushes self into the corresponding output sink in outputs.

fn poll_flush( outputs: &mut Outputs, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Call poll_flush on all Outputs.

fn poll_close( outputs: &mut Outputs, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Call poll_close on all Outputs.

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.
