Speed up Rust Builds with Cachepot

One of the most effective ways for speeding up Rust builds is to cache the compiled artifacts of crate dependencies. Cargo does this automatically for local builds, but this quickly breaks down for distributed scenarios.

In this post, I will share my experiences with configuring and using Cachepot, a tool which wraps the Rust compiler and automatically caches build artifacts using a variety of cloud storage options. This creates a cache which can be shared amongst teams, used in ephemeral CI/CD environments, and even used for distributed builds.
