Module bytes 

Bytes and Buffer Management

Zero-copy buffer types providing the foundation for efficient network I/O, codec implementations, and protocol parsing.

Overview

This module provides:

• Bytes: Immutable, reference-counted byte slice with cheap cloning
• BytesMut: Mutable buffer with efficient growth and splitting
• Buf: Trait for reading bytes from a buffer
• BufMut: Trait for writing bytes to a buffer

Design Notes

Unlike the bytes crate, this implementation uses safe Rust throughout, avoiding raw pointers in favor of Arc<Vec<u8>> and Vec<u8>. This trades some performance for safety, alignment with asupersync’s #![forbid(unsafe_code)] policy, and simplicity.

Cancel-Safety

Buffer operations are synchronous and thus inherently cancel-safe. No async operations are involved in buffer manipulation.
