A Few More Reasons Rust Compiles Slowly

Re:A Few More Reasons Rust Compiles Slowly by sk0g on Monday June 29, 2020 @11:08PM (#23686086)

The backend service I'm using doesn't have cached CI yet, so the entire build takes ~20 seconds. The CircleCI free tier is good enough for now, and more time is spent pulling dependencies than building, anyway. The build pulls in heaps of dependencies, and the main codebase itself being around 20kloc. Subsequent local builds take around .2 seconds locally, so I'm very happy with it. Even working on a tiny Java/ Kotlin codebase recently made me miss the good compile times!

How hard is the caching to set up, especially in a CI setting?

It depends - at my work we use buildkite which is a “bring your own runners” build service, so caching is available by default, so long as the cache is outside of the project directory. For personal stuff I use GitHub and Gitlab - they both offer caching. GitHub’s offering is easier but Gitlabs is just as effective.

Cargo caches by default and you can specify the path that it stores artifacts. Most of the cache story is about what your chosen provider uses to specify build steps, etc
