bufkit 0.5.1 - Docs.rs

no_std-friendly, memory-backed buffer toolkit designed for Sans-I/O style encoding and decoding. Provides Chunk (read-only view), ChunkMut (mutable view), and helpers for explicit, convenient bounds-checked access.

Overview

bufkit is a small, focused toolkit for working with in-memory buffers in a predictable, controlled way.
It’s Sans-I/O friendly — meaning it’s easy to integrate into network protocol parsers, database engines, binary file format decoders/encoders, and embedded systems that follow the Sans-I/O design pattern — but it doesn’t implement any I/O itself.

Features

Predictable memory usage – operates directly on memory you provide, no hidden allocations.
Explicit error handling – choose panicking, Option, or detailed Result with requested vs. available byte counts.
Segmented views – create independent Chunk/ChunkMut views into the same buffer.
Offset reads/writes – operate at arbitrary positions without unsafe pointer math.
Embedded friendly - no_std & no_alloc ready – works in embedded and constrained environments.
Retry-friendly – try_* methods enable robust partial read/write handling.
