Rust Types

rust-types is a TypeScript library providing Rust-like Result and Option types for handling success or failure and optional values, respectively.

Why another one

I tested many of these libraries, and my personal conclusion is that https://github.com/vultix/ts-results have the best api in the context/limitation of typescript. That library haven't been updated in a while (also latest version didn't work for me) so it was a good execuse to add my own.

Usage

Result

The Result type represents either success with a value or failure with an error.

import { Err, Ok, Result } from "jsr:@sigmasd/rust-types/result";

const result = Ok(41); // Result with value 41
const errorResult = Err("Something went wrong"); // Result with error

Option

The Option type represents an optional value that may or may not exist.

import { Option } from "jsr:@sigmasd/rust-types/option";

const option = Option.wrap(41); // Option with value 41
const emptyOption = Option.wrap(null); // Empty Option
