cargo-xtask-example

This is an example repository for cargo xtask. For more information on @matklad's cargo xtask pattern, visit the original repository.

Quickstart

In the root of the repository, run the following command:

cargo xtask

A list of "tasks" should print alongside their descriptions. This command works via an alias in the repository's cargo configuration file.

Repository Structure

This repository contains two crates: xtask and your-crate. The former contains the "tasks" and ability to run them. The latter represents the crate(s) that xtask would help orchestrate "tasks" for.

Why cargo xtask?

Using external build systems and scripting languages can be useful, but using these technologies can result in inaccessible contributing experiences and potentially locking out valid development environments.

Since cargo is the tried and true build system for Rust (tested on multiple tiered targets), we can get the best of both worlds by using a small wrapper around it. Thus, cargo xtask exists to fill the gap; allowing for repository automation without needing to install another dependency.
