Readme

bin_io

LICENSE Crates.io Version

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 = "0.2" to your Cargo.toml

Big change in 0.2

In 0.2 bin_io had a massive change, it now uses references while writing, and no longer needs an owned copy. This meant that some things needed to change from the last version, but everything should still work fine (with minor code changes, seq! in particular), so check out the documentation!

Example

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

#[derive(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, thing_parser())
    .unwrap();

cursor.set_position(0);

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

assert_eq!(other_thing, my_thing);
