Install

cargo install --locked rust-toolchain-manifest

Downloads the official rust release manifests, parses them and saves them as json objects.

Usage:

rust-toolchain-manifest [CHANNEL]

The channel can be either stable, beta, or nightly.

For beta and nightly channels components are split up into the date of the channel [CHANNEL]/[YEAR]/[date].json and a map [CHANNEL]/[YEAR]/since[date]-map.json, that can potentially be reused by further channel updates, in order to not save unnecessary state.

The tree of a channel will potentially look like this:

   nightly
   └── 2022
       ├── 2022-10-05.json
       ├── 2022-10-06.json
       ├── 2022-10-07.json
       ├── metadata.json
       └── since-2022-10-05-map.json

• metadata.json: Saves state about the current channel.
• [date].json: Saves state on the channel on the specified [date].
• since-[date]-map.json: A helper map, that allows the [date].json snapshots of channels to be fairly small.
