Available on crate feature dfir_macro only.

Trait for use with the demux_enum operator (Push-based version).

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 Push that corresponds to each of the variants of the tuple, in alphabetic order.

Required Associated Types

type Ctx<'ctx>: Context<'ctx>

The context type, inherited from the downstream pushes.

type CanPend: Toggle

Whether this push can return [PushStep::Pending], inherited from the downstream pushes.

Required Methods

fn poll_ready( outputs: &mut Outputs, ctx: &mut Self::Ctx<'_>, ) -> PushStep<Self::CanPend>

Poll readiness of all output pushes.

fn start_send(self, meta: Meta, outputs: &mut Outputs)

Pushes self into the corresponding output push in outputs.

fn poll_flush( outputs: &mut Outputs, ctx: &mut Self::Ctx<'_>, ) -> PushStep<Self::CanPend>

Flushes all output pushes.

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.
