typerust

A library that provides Rust types in TypeScript. This library contains TypeScript implementations of the following Rust types: Result, Option, HashMap, and HashSet.

Installation

# deno
deno add npm:typerust
# npm
npm install --save-dev typerust

Usage

Result

import { Result } from "typerust";

const success = Result.Ok(42);
const failure = Result.Err("something went wrong");

if (success.isOk()) console.log(success.unwrap());

const fromPromise = Result.from(Promise.resolve(100));

Option

import { Option } from "typerust";

const some = Option.Some(10);
const none = Option.None;

if (some.isSome()) console.log(some.unwrap());

const fromNullable = Option.from(null);

HashMap

import { HashMap } from "typerust";

const map = HashMap.from({ key: "value" });
const entry = map.get("key");

if (entry) console.log(entry.value);

HashSet

import { HashSet } from "typerust";

const set = HashSet.from([1, 2, 3]);
const exists = set.contains(2);

if (exists) console.log("Found 2");
