The SCALE (Simple Concatenated Aggregate Little-Endian) Codec is a lightweight, efficient, binary serialization and deserialization codec.

It is designed for high-performance, copy-free encoding and decoding of data in resource-constrained execution contexts, like the Substrate runtime. It is not self-describing in any way and assumes the decoding context has all type knowledge about the encoded data.
