Typescript Rust-Like Utility Types

A Typescript library that provides utility types inspired by Rust's powerful type system, including Result<T, E> and Option<T>. These types help to enhance type safety and improve error handling in Typescript applications.

Installation

You can install the library via npm:

npm i @dbidwell94/ts-utils

yarn add @dbidwell94/ts-utils

pnpm add @dbidwell94/ts-utils

Quick Start

Option

import { option, Option } from "@dbidwell94/ts-utils";

const myOption = option.some(123);

function doSomethingWithOptions(optionParam: Option<number>) {
  if (optionParam.isSome()) {
    console.log(`Option value is ${optionParam.value}`);
  } else {
    console.log("The provided Option has no value");
  }
}

doSomethingWithOptions(myOption); // Option value is 123
doSomethingWithOptions(option.none()); // The provided Option has no value

function doSomethingNullishValue(val: number | null | undefined) {
  doSomethingWithOptions(option.unknown(val));
}

doSomethingNullishValue(null); // The provided Option has no value

Result

import { result, Result } from "@dbidwell94/ts-utils";

const myResult = result.ok(123);

function doSomethingWithResult(resultParam: Result<number>) {
  if (resultParam.isOk()) {
    console.log(`The provided value was ${resultParam.value}`);
  } else {
    console.log(
      `The provided Result errored with ${resultParam.error.toString()}`,
    );
  }
}
