HeaderOffsets
HeaderOffsets is a construct used in data parsing and file format design to record the starting byte positions of header fields within a data stream. It functions as an index that enables fast access to individual header components without sequentially scanning the entire payload. HeaderOffsets are commonly represented as a collection of integer offsets paired with field identifiers, with offsets typically measured in bytes from the beginning of the message or file.
The primary purpose of a header offsets structure is to improve parsing performance and support random access
Common representations include an array or map that associates field names or tags with their respective offsets.
Typical use cases include binary file formats, network protocols, and embedded systems where rapid header access
