mr boxingtonBuild it once.

A Cargo wrapper that shares compiled work across worktrees and CI—and prunes build storage automatically.

Wrap normal Cargo commands

Put mbx before build, test, or clippy. Cargo still plans the build; mbx restores the rustc work it has seen before.

Cache keys contain no checkout-specific absolute paths, so building one checkout warms its siblings automatically.

Use a remote cache or GitHub Actions cache while untrusted pull requests remain read-only.

Keep the cache inside a size budget and reclaim managed target directories after their checkout disappears.

Experimental

mr boxington is pre-1.0. The cache format and behavior may change without notice, and releases are not a stability promise.
