## What it is
A Rust crate providing convenience methods for encoding and decoding numbers in big-endian or little-endian byte order. It extends the standard Read and Write traits with endian-aware numeric methods and supports no_std environments.

## Use cases
- read and write integers in little-endian or big-endian byte order
- parse binary file formats with specific endianness
- serialize numbers for network protocols
- decode binary data from a byte stream in Rust
- use endian-aware number encoding in a no_std embedded project

## When to choose
- you need endian-aware reading/writing of numbers over io::Read/io::Write streams
- you are working with binary file formats or network protocols in Rust
- you need a lightweight, no_std-compatible serialization helper

## When to avoid
- you only need simple conversions like to_le_bytes/from_le_bytes available in the Rust standard library since 1.32
- you need full struct serialization rather than raw number encoding

## Facets
- artifact type: library
- maturity: stable
- function: serialization
- domain: developer-tools, files
- platform: rust, cross-platform
- tags: byte-order, endian, binary-format, no-std, rust-crate
