binwrite

A Rust crate for helping write structs as binary data using ✨macro magic✨

Usage

BinWrite uses a derive macro for declaratively defining binary writing methods for structs.

Basic Example

```rust use binwrite::BinWrite;

[derive(BinWrite)]

[binwrite(little)]

struct Rect { x: i32, y: i32, #[binwrite(big)] size: (u16, u16), }

fn main() { let rects = vec![ Rect { x: 1, y: -2, size: (3, 4) }, Rect { x: 20, y: 4, size: (5, 7) } ]; let mut bytes = vec![]; rects.write(&mut bytes).unwrap(); assert_eq!( bytes, vec![ // [ x (little endian) ] [ y (little endian) ] [ size.0 ] [ size.1 ] 0x01, 0x00, 0x00, 0x00, 0xFE, 0xFF, 0xFF, 0xFF, 0x00, 0x03, 0x00, 0x04, 0x14, 0x00, 0x00, 0x00, 0x04, 0x00, 0x00, 0x00, 0x00, 0x05, 0x00, 0x07, ] ); } ```
