Trait combine::stream::ResetStream

pub trait ResetStream: StreamOnce {
    type Checkpoint: Clone;

    // Required methods
    fn checkpoint(&self) -> Self::Checkpoint;
    fn reset(&mut self, checkpoint: Self::Checkpoint) -> Result<(), Self::Error>;
}

A StreamOnce which can create checkpoints which the stream can be reset to

Required Associated Types

type Checkpoint: Clone

Required Methods

fn checkpoint(&self) -> Self::Checkpoint

Creates a Checkpoint at the current position which can be used to reset the stream later to the current position

fn reset(&mut self, checkpoint: Self::Checkpoint) -> Result<(), Self::Error>

Attempts to reset the stream to an earlier position.

Object Safety

This trait is not object safe.
