Download .crate files of all versions of all crates from crates.io.
Useful for things like noisy-clippy which need to analyze the source code of all crates.
I wrote this tool to saturate a 1000 Mbps connection. From scratch, it can finish downloading in under 20 minutes. It can also check the checksums of a directory of downloaded crates in 40 seconds on 64 cores. For a more fully featured tool, which some of this code is based on, but which is much slower in my experience, check out https://git.shipyard.rs/jstrong/registry-backup.
$ cargo install get-all-crates
$ git clone https://github.com/rust-lang/crates.io-index /path/to/index
$ get-all-crates --index /path/to/index --out /path/to/cratesWarning: as of 2022 this writes out more than 100 GB of crates.
The output directory structure is similar to how Cargo's registry index is structured:
