Usage

BufferMap

The BufferMap follows the same interface as Map so you can use it exactly as you would normally use a Map object with the only difference being that the keys are only Uint8Arrays and the value of the array is used as the key instead of the instance itself.

import { BufferMap } from "@organicdesign/buffer-collections";

const map = new BufferMap();

const key = new Uint8Array([1]);
const value = "value";

map.set(key, value);

console.log(map.has(new Uint8Array(key))); // true
console.log(map.get(new Uint8Array(key)) === value); // true

You can also type the values with TypeScript like so:

new BufferMap<string>();

TODO
