Data Modules

This section documents xutils/src/data/*.

Files

• array.md: dynamic array with optional pool-backed ownership
• buf.md: byte buffers, pointer buffers and ring buffers
• hash.md: chained hash table keyed by integer hash
• json.md: JSON parser, builder and formatter
• jwt.md: JSON Web Token creation, parsing and verification
• list.md: doubly linked list utilities
• map.md: open-addressing key/value map
• str.md: string helpers, tokenization, formatting and dynamic string routines

Common Rules

• Several containers can either copy payloads or take ownership of an external pointer. The docs call out the difference because it is not uniform across the API surface.
• Pool-backed storage is common. Resetting or destroying a pool-backed container invalidates every pointer allocated from that pool.
• JSON, JWT and HTTP-related code heavily reuse buf, array, map and str.
