Variant Integer, Variant String, Async and Non-Async supported

variant-encoding

This crate provides encoding and decoding of integers and variant strings to and from bytestring representations.

The format is described here: Google's protobuf integer encoding technique.

VarInt

VarInt encodes integers in blocks of 7 bits; the MSB is set for every byte but the last, in which it is cleared.

Signed values are first converted to an unsigned representation using zigzag encoding (also described on the page linked above), and then encoded as every other unsigned number.

VarString

VarString encodes a VarInt and a string of u8 of the length of the VarInt
