Small thing I built in my spare time that has really helped agentic rust development: github.com/RhizoNymph/rust-b… It uses Kache backed by minio to set up a remote build server and shim all cargo commands (configurable what commands stay local) to run through it. If it can't reach it, it uses a local Kache instance instead and settles up the build artifacts when it can see it again. It also has a bootstrap command to set up the server and any number of clients as long as you have ssh access to them. Before I had this I always told my agents not to let subagents run rust builds because they were killing my laptop doing it in parallel but this fixed that entirely by introducing the caches and a build queue.
