cargo-spellcheck
Check and fix spelling and grammar in your code documentation using hunspell and nlprule.
Catch spelling and grammar mistakes in your Rust documentation comments.
cargo-spellcheck is a cargo plugin that scans your codebase for spelling and grammar errors. It is built for Rust developers who want to maintain clean documentation without manual proofreading.
What it is
The tool parses your source tree and runs checks using hunspell and an nlprule-based grammar checker. You can run checks in your CI/CD pipeline or interactively apply suggestions to your documentation comments.
