The decision to rewrite StelLang in Rust was driven by a commitment to performance, safety, and maintainability. This post shares the story, challenges, and lessons learned from this ambitious rewrite.

Why Rust?​

  • Memory Safety: Rust's ownership model prevents many common bugs.
  • Performance: Rust delivers C-like speed with modern ergonomics.
  • Ecosystem: Leverage powerful crates and tooling.

The Rewrite Process​

  1. Planning: Identified core features and designed new syntax.
  2. Implementation: Rebuilt the interpreter, parser, and standard library in Rust.
  3. Refactoring: Improved code structure, error handling, and extensibility.

Challenges Faced​

  • Adapting to Rust's strictness
  • Migrating existing features
  • Ensuring compatibility and performance

The Results​

  • Faster execution
  • Fewer bugs
  • Easier to maintain and extend

Rewriting in Rust was a turning point for StelLang. The journey continues—thank you for being part of it!
