Options

• Use https://raw.githubusercontent.com/rust-lang/rust/master/RELEASES.md
  • Only stable versions
  • Should still check channel manifest for latest version, since the upcoming release may be included in RELEASES.md
• Parse from (historical) channel manifests
  • Historical manifests indexed at: https://static.rust-lang.org/manifests.txt
  • Requires downloading, parsing and assembling a lot of smaller files to a create an index; depending on the connection speed, limiting, etc., the speed of this process may vary
• Download S3 index
  • Manual: aws --no-sign-request s3 ls static-rust-lang-org/dist/ > dists.txt
  • Slow download, heavily rate limited, approx 45s currently
  • One big index

Progress:

• Ability to index stable, beta, nightly versions using second option (Parse from (historical) channel manifests)
• Proof of concept repo: https://github.com/foresterre/manifesta
• Downloading all indexes is severely rate limited (30-120sec for stable channel manifests), and the release manifests are sufficiently large that parsing them, even though we only need a small part takes a few seconds
