link2xt	d75c05e717	ci: do not store Rust cache from PRs <https://github.com/swatinem/rust-cache> caches only dependencies, and dependencies don't change most of the time, so PRs store the same cache as already stored by the main branch commit PRs are based on. Hash of Cargo.{toml,lock} is part of the cache key, so for dependency updating PRs the cache key is new. Such PRs rebuild everything from scratch, which is a separate problem. Storing such cache from PR is however not useful because most of the time dependency updating PR is going to be rebased again before merging as Dependabot PRs are opened in a batch and then merged one by one while Dependabot rebases remaining PRs.	2026-05-04 11:21:33 +00:00
