Rust's str module in TypeScript

We have 23 Rust functions so far - help us add more

Got a rainy Sunday afternoon and a taste for a porting puzzle?

  • Get inspiration from the Rust std::str docs.
  • Click "New file" in the appropriate folder on GitHub. This will fork the project to your account, directly add the file to it, and send a Pull Request to us.

We will then review it. If it's useful to the project and in line with our contributing guidelines your work will become part of Locutus and you'll be automatically credited in the authors section accordingly.

Remaining string helpers are useful plain-value portability targets unless they depend on iterators or byte semantics.

  • rmatches Skip Iterator-returning APIs do not fit Locutus' plain-value model.
  • trim_matches Skip Pattern-driven trimming does not map cleanly to one stable plain-value contract.
