rustup-mirror

Setup a local rustup mirror. For usage, please run rustup-mirror -h.

How to install

Run cargo install rustup-mirror.

Features

1. Check if file is already downloaded and check its integrity by comparing sha256 checksum.
2. Download and replace links in the manifest files.
3. Use --keep to choose which compression format(s) to mirror (e.g. --keep xz or --keep gz; default is xz only). Unkept archives are removed from the served manifest and their already-mirrored files are deleted, saving disk space. rustup prefers zst > xz > gz when listed, so installs still work.

Example usage

$ rustup-mirror # use HTTPS_PROXY for proxy
$ # wait for downloading
$ cd ./mirror # default directory, see rustup-mirror -h
$ python3 -m http.server &
$ RUSTUP_DIST_SERVER=http://127.0.0.1:8000 rustup install stable

Note:

1. A full clone of a stable distribution takes 16G disk space (as of Feb 2019).
2. Python3 http.server module does not support Range download. It may fail when a partial downloaded file exists. Do not use this in production.
