This is a Kotlin Multiplatform line-by-line transliteration port of byteorder.

Original Project: This port is based on byteorder. All design credit and project intent belong to the upstream authors; this repository is a faithful port to Kotlin Multiplatform with no behavioural changes intended.

This is an in-progress port. The goal is feature parity with the upstream Rust crate while providing a native Kotlin Multiplatform API. Every Kotlin file carries a // port-lint: source <path> header naming its upstream Rust counterpart so the AST-distance tool can track provenance.

The text below is reproduced from https://github.com/BurntSushi/byteorder. It is the upstream project's own description and remains under the upstream authors' authorship; links have been rewritten to absolute upstream URLs where appropriate so they continue to resolve from this repository.

This crate provides convenience methods for encoding and decoding numbers in either big-endian or little-endian order.

Dual-licensed under MIT or the UNLICENSE.

https://docs.rs/byteorder

This crate works with Cargo and is on crates.io. Add it to your Cargo.toml like so:

[dependencies]
byteorder = "1"

If you want to augment existing Read and Write traits, then import the extension methods like so:

use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};

For example:

use std::io::Cursor;
use byteorder::{BigEndian, ReadBytesExt};

let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
// Note that we use type parameters to indicate which kind of byte order
// we want!
assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());

This crate has a feature, std, that is enabled by default. To use this crate in a no_std context, add the following to your Cargo.toml:

[dependencies]
byteorder = { version = "1", default-features = false }

Note that as of Rust 1.32, the standard numeric types provide built-in methods like to_le_bytes and from_le_bytes, which support some of the same use cases.
