Algebraic Tag Length Value encoding for Rust

atlv is a generic binary data encoding that preserves the data's leaf-spine structure while providing customizable tags and dictating minimal semantics.

value:	quant | binary | union | array
quant:	tag…00(vlq) (vlq)
binary:	tag…01(vlq) len(vlq) byte[len]
union:	tag…10(vlq) value
array:	tag…11(vlq) len(vlq) value[len]
vlq:	0xxxxxxx | 1xxxxxxx vlq
byte:	xxxxxxxx
tag:	xxxxx | xxxxxxx tag

This repository contains a Rust crate for encoding, decoding, and generally manipulating atlv data.

lib.rs:

Encode and decode atlv values.

Algebraic Tag Length Value (atlv) is a binary data encoding designed for extensibility, generality, and compactness. Each value has a flexible-length tag, and may be one of four [Kind]s, two simple and two recursive:

• Quantities encode enumerable values, using Variable Length Quantities.
• Binaries encode sequences of bytes.
• Unions encapsulate a single value.
• Arrays encapsulate a sequence of values.

This crate provides a trait to encode and decode rust values directly into atlv streams, and a type to model and genericly encode and decode arbitrary atlv values. Use the trait unless you need to manipulate or examine unstructured atlv values.
