The article introduces kache, a Rust build cache tool developed by Kunobi to speed up development workflows. It works as a RUSTC_WRAPPER that caches compilation artifacts based on source code, dependencies, and toolchain contents, enabling faster builds across different worktrees and CI environments. The tool uses content-addressable storage and filesystem reflinks for efficient artifact sharing.
Background
Rust's build times have been a known pain point in the developer community, especially for large projects with complex dependency trees. While cargo's built-in incremental compilation helps with local rebuilds, it doesn't address the need for sharing compiled artifacts across different development environments or CI systems.
