bin_io

bin_io is a crate inspired greatly by nom and other parser combinator libraries. But bin_io differs from those crates since it aims at providing both reading and writing facilities at the same time, with fewer code.

Usage

Add bin_io = "0.1" to your Cargo.toml

Example

use std::io::Cursor;
use bin_io::{ boilerplate, seq, read, write };
use bin_io::numbers::{ be_u8, be_u16 };

# #[derive(Clone, Debug, PartialEq, Eq)]
struct Thing {
    a: u8,
    b: u16
}

boilerplate!(
    fn thing_parser() -> Thing {
        seq!(
            Thing { a, b },
            a: be_u8() =>
            b: be_u16() =>
        )
    }
);

let mut vec = Vec::new();
let mut cursor = Cursor::new(vec);

let my_thing = Thing {
    a: 0x10, b: 0x20
};

write(&mut cursor, my_thing.clone(), thing_parser())
    .unwrap();

cursor.set_position(0);

let other_thing = read(&mut cursor, thing_parser())
    .unwrap();

assert_eq!(other_thing, my_thing);
