Restructure is a JavaScript library that lets developers describe binary formats declaratively and then automatically encode to and decode from `Uint8Array` buffers. It provides a rich set of built‑in types—numbers, strings, enums, bitfields, arrays, pointers, versioned structs, etc.—and a simple API (`fromBuffer`, `toBuffer`, `size`) for working with complex binary structures without writing custom parsers, making it ideal for Node.js or browser projects that need to handle binary protocols, file formats, or low‑level data interchange.
