better typescript enums (also Option<T>, Result<T, E>)

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.
