Crate streamline

This crates provides a state machine implementation that emits states as a std::futures::Stream, groups sources of external state into a single Context, and handles automatic conversion between states (both forwards and backwards) through the State trait.

Structs

Cancellation handle returned by run_preemptible that can be used to trigger Streamline revert processes from outside the next method

Streamline

Streamlines represent the streams of states configured for a particular Context, Error type, and State-implementing type

Enums

Progress

The state emitted by a Streamline

RevertProgress

An internal state machine that represents the process of reverting previous progress.

Traits

State

The State trait defines the way that a Streamline progresses to (or from) the next state.
