When working with variable-length encodings for numbers, the buffers themselves become variable length, and it is impossible to check that they are long enough before decoding them. Fixed-length buffer layouts have obvious benefits, but if some protocol uses var-length encoding, buffer underflow can occur even when reading fixed-length numbers.

This trait provides functionality for decoding numbers using fixed-length encodings, but checking for buffer underflow.
