Crate topograph 

A tiny library offering a concurrent work queue for synchronous or asynchronous tasks, as well as an implementation of topological sort built on top of it

This crate contains two main components, each with their own (slightly different) use cases:

• executor contains the core logic for the work queue, as well as the necessary types and logic to initialize it
• graph is a topological sort implementation for handling more complex cases with inter-task dependencies

The documentation for each of the above modules contains example code for each use case.

Modules

executor

Functionality for constructing and running work-queue executors

graph

A concurrent implementation of topological sort (toposort, for short) for handling task dependencies

prelude

Common traits used when working with topograph

Traits

AsyncHandler

A trait to work around the inability to express async lifetimes with Fn

ExecutorBuilder

Builder type for a work queue executor

ExecutorBuilderAsync

Helper trait for describing an ExecutorBuilder that can accept any AsyncHandler as a synchronous task

ExecutorBuilderCore

Trait describing common types for both ExecutorBuilderSync and ExecutorBuilderAsync

ExecutorBuilderSync

Helper trait for describing an ExecutorBuilder that can accept any Fn as a synchronous task

ExecutorCore

Abstraction over a concurrent work queue executor

ExecutorHandle

The smallest common abstraction over a work queue and associated task handle, providing solely a push function
