blurhash-rust-wasm

A Rust implementation of the blurhash algorithm.

It is compiled to WebAssembly (WASM), and available on npm as blurhash-wasm.

Usage in JS

import * as blurhash from "blurhash";

// Returned as Uint8Array
// You can use this to construct canvas-compatible resources
const pixels = blurhash.decode("LKO2?U%2Tw=w]~RBVZRi};RPxuwH", 40, 30);

Usage in Rust

decode

use blurhash_wasm;

// Result<Vec<u8>, blurhash::Error>
let res = blurhash::decode("LKO2?U%2Tw=w]~RBVZRi};RPxuwH", 40, 30);

encode

About the setup

Based on the rust wasm-pack template

This template is designed for compiling Rust libraries into WebAssembly and publishing the resulting package to NPM.

Be sure to check out other wasm-pack tutorials online for other templates and usages of wasm-pack.

🚴 Usage

🛠️ Build with wasm-pack build

wasm-pack build

🔬 Test in Headless Browsers with wasm-pack test

wasm-pack test --headless --firefox

🎁 Publish to NPM with wasm-pack publish

wasm-pack publish

🔋 Batteries Included

• wasm-bindgen for communicating between WebAssembly and JavaScript.
• console_error_panic_hook for logging panic messages to the developer console.
• wee_alloc, an allocator optimized for small code size.
