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