Troubleshooting & FAQ

1. Common Issues

❗ Sparse index directory not found

Make sure you cloned it properly:

git clone https://github.com/rust-lang/crates.io-index.git sparse-index

❗ 429 Too Many Requests

Solutions:

  • Use an authenticated token:
CRATES_IO_TOKEN=<token>
  • Reduce frequency of runs
  • Let caches handle daily refreshes

❗ Failed to parse cache

Fix:

rm cache/index_cache.json
rm cache/crates_cache.json
cargo run -- -s sparse-index

❗ Resume not working

Use:

cargo run -- -s sparse-index --force-fresh

2. FAQ

💬 Why is the first run slow?

Because it fetches metadata for all crates depending on Ratatui.

Subsequent runs are extremely fast.

💬 Why isn’t my crate included?

Possible reasons: It doesn’t depend on ratatui It uses optional dependency incorrectly It has only yanked versions with that dependency

💬 How often should I run this?

Daily or weekly.

💬 Will the JSON format change?

Minor changes are possible. The schema chapter documents stable and unstable fields.
