Trait Emit 

pub trait Emit {
    type Item;

    // Required method
    fn emit(&mut self, item: Self::Item) -> Result<(), EmitError>;
}

Object-safe handle to push items downstream from inside crate::Stage::process.

Required Associated Types

type Item

The type of item this handle accepts.

Required Methods

fn emit(&mut self, item: Self::Item) -> Result<(), EmitError>

Push one item downstream.

Errors

Returns EmitError::Closed when the downstream has shut down (often because a later stage produced an error and the driver is unwinding). Returns EmitError::WouldBlock under a non-blocking driver if the downstream buffer is full.
