# cargo-build-dependencies

[![Crates.io](https://img.shields.io/crates/v/cargo-build-dependencies.svg)](https://crates.io/crates/cargo-build-dependencies)

This tool extends [Cargo](https://doc.rust-lang.org/cargo/) to allow you to

build only the dependencies in a given rust project. This is useful for docker

builds where each build step is cached. The time it takes to build dependencies

is often a significant portion of the overall build time. Therefore it is

beneficial in docker builds to build dependencies in a separate step earlier

than the main build. Since the dependency building step will be cached,

dependencies will not need to be rebuilt when the project's own source code

changes.
