Rust teams struggle with inconsistent code styles across contributors. A linter could automatically check code against Google's newly published style rules.
Create a CLI tool or editor plugin that flags deviations. It should support gradual adoption with configurable strictness levels.
Rust teams at scale would pay for time saved in code reviews. Open source could use a free tier.
Start with core formatting rules like imports and line lengths. Expand to idioms over time.
The risk is competing with existing Rust linters that might add style rules themselves.
