Cargo Bloat Action 🚀

Analyse and track your Rust project binary size over time. This action runs on every pull request and gives you a breakdown of your total binary size, how much each crate contributes to that size and a list of changes to your dependency tree.

Size difference per crate

Changes in your dependency tree (cargo tree)

Why?

I think it's important to track the size of your dependencies. It's not the most important thing, but I think these metrics belong in a pull request that modifies dependencies in order to have a full picture of the impact the change makes and to make an informed decision before merging.
