Description
This PR adds a new rust checker to detect the use of
.unwrap()in Rust code. While.unwrap()is convenient, it can lead to unexpected panics and is only meant for quick prototyping (see rust error handling). This checker is flagged as anantipatternsince it does not impact security much.Detection Logic
The checker flags the following cases:
.unwrap()on anOptionorResultRecommended Alternatives
Instead of using
.unwrap(), consider:matchorif let.unwrap_or_else()to provide a fallback value or handle errors gracefully.expect()with a meaningful message if a panic is intentionalExclusions
To reduce noise, the checker does not flag occurrences in test files, vendor dependencies, or test directories.
