BinData
BinData is a term used in computing to describe libraries, modules, or design patterns that model and manipulate binary data in a structured way. The central idea is to describe a binary layout—fields with fixed or variable sizes, bit-level fields, endianness, alignment—and to read from or write to streams accordingly. BinData-style tools are commonly used when dealing with binary file formats, network protocols, or any data interchange requiring precise control over bits and bytes.
The best-known usage is the BinData module for the Perl programming language. This module provides a declarative,
Similar capabilities exist in other ecosystems under different names. For example, Python developers sometimes use libraries
Common applications include protocol parsers, binary file format tooling, data capture and analysis, and test utilities
