Crate commonware_runtime

Execute asynchronous tasks with a configurable scheduler.

This crate provides a collection of runtimes that can be used to execute asynchronous tasks in a variety of ways. For production use, the tokio module provides a runtime backed by Tokio. For testing and simulation, the deterministic module provides a runtime that allows for deterministic execution of tasks (given a fixed seed).

Status

commonware-runtime is ALPHA software and is not yet recommended for production use. Developers should expect breaking changes and occasional instability.

Modules

• deterministic
  A deterministic runtime that randomly selects tasks to run based on a seed
• mocks
  A mock implementation of a channel that implements the Sink and Stream traits.
• tokio
  A production-focused runtime based on Tokio with secure randomness and storage backed by the local filesystem.

Structs

• Handle
  Handle to a spawned task.
• Signaler
  Coordinates a one-time signal across many tasks.

Enums

• Error

Traits

• Blob
  Interface to read and write to a blob.
• Clock
  Interface that any task scheduler must implement to provide time-based operations.
• Listener
  Interface that any runtime must implement to handle incoming network connections.
• Network
  Interface that any runtime must implement to create network connections.
• Runner
  Interface that any task scheduler must implement to start running tasks.
• Sink
  Interface that any runtime must implement to send messages over a network connection.
• Spawner
  Interface that any task scheduler must implement to spawn sub-tasks in a given root task.
• Storage
  Interface to interact with storage.
• Stream
  Interface that any runtime must implement to receive messages over a network connection.

Functions

• reschedule
  Yield control back to the runtime.

Type Aliases

• Signal
  A one-time broadcast that can be awaited by many tasks. It is often used for coordinating shutdown across many tasks.
