Solana Bytes Reader

A lightweight, ergonomic utility library for safely and efficiently reading bytes slices, primarily designed for Solana program development.

This crate provides basic primitives for reading various integer types, booleans, and fixed-size byte arrays from raw byte slices with offset tracking.

Features

• Safe, offset-aware reading of primitive types (u8, i8, u16, i16, u32, i32, u64, i64).
• Boolean reading with validation.
• Support for reading fixed-size byte arrays.
• Optional zero-copy deserialization for Pod types via the bytemuck feature.
• Traits for reading (ReadBytes) and peeking (PeekIntoBytes) without advancing the offset.

Usage

Add to your Cargo.toml:

# Enables basic features (by default)
solana-bytes-reader = "0.2.0"

# Enables `bytemuck` feature (disabled by default)
solana-bytes-reader = { version = "0.2.0", features = ["bytemuck"] }

Example

Initialize a Reader with a byte slice and use the provided methods to parse data sequentially or peek into upcoming bytes without consuming them.

use solana_bytes_reader::{Reader, ReadBytes};

let data: &[u8] = /* your byte slice */;
let mut reader: Reader = Reader::new(data);

let value: u32 = reader.read_u32()?;
let flag: bool = reader.read_bool()?;
// ...
