A drop-in replacement for the cargo command that makes Rust builds faster, with nothing to configure. Every build goes into one centrally managed cache, which stays within its limits and gives space back on its own as the disk fills, so Rust builds don't fill up your disk. QuickRust brings its own toolchains, runs the toolchain's own Cargo and rustc, and records every build, so it can tell you where the time and the disk space went.
