Show HN: QuickRust replaces cargo, sets up sccache, centralizes build cache

QuickRust

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.

All downloads Your first build Commands All documentation

$ cargo build OK Built: 12 compiled, 140 fresh, 37 restored from QuickRust's cache [4.21s] WARN 23 warnings in app and util: unused_variables x17, dead_code x4, unused_imports x1, +1 more; qrust warnings shows them

and then, about that build

Faster by default

Lighter debug information, rustc's parallel frontend, a shared artifact cache and early cut-off. The program you build behaves exactly the same.

No target/ in your projects: builds live in one central cache shared by every checkout. It keeps under a size limit and, as the disk fills, frees the least recently used first.

One status line, errors in full, warnings counted and kept, one line per outcome.

The critical path, why each crate rebuilt, duplicated dependencies, build scripts and macros, cache behaviour, disk use.

It downloads and manages Rust toolchains itself: rust-toolchain.toml and +toolchain choose, as with rustup.
