Encode and decode Protobuf-style varint bytes from a buffer.
Fork of chrisdickinson's varint npm package.
// Encoding a varint...
{
const buffer = new Uint8Array(16);
const written = encode(300, buffer, 0);
// -> 2 bytes written
console.log(buffer.subarray(0, written));
// -> Uint8Array(2) [0xAC, 0x02]
}
// Decoding a varint...
{
const buffer = new Uint8Array([0xAC, 0x02]);
const [num, read] = decode(buffer, 0);
// -> 2 bytes read, got 300
}
