crabrave

near-zero-cost abstractions ported from Rust to TypeScript

features:

very simple API that closely follows Rust's
rust style enums with packed data
Option<T> and Result<T> types
match(), matchPartial(), and unwrap()
about as performant as doing the comparisons by hand
very lightweight, you won't notice it's even there in prod
works in all environments (browser, node, bun, deno)
(soon) helpers to wrap existing functions
(soon) wrappers over built-in web APIs and external libraries (a very simple and incomplete fetch wrapper is already included)

Check /test for code examples.

To install development dependencies:

bun install

To run:

bun run index.ts

To test:

bun test

This project was created using bun init in bun v1.0.7. Bun is a fast all-in-one JavaScript runtime.
