Build Status

A fast binary serialization framework

Documentation

The goal of this crate is to provide fast, simple and easy binary serialization.

Benchmarks

See serde-bench for benchmarks.

Example

#[macro_use]
extern crate speedy_derive;
extern crate speedy;

use std::borrow::Cow;
use speedy::{Readable, Writable, Endianness};

#[derive(PartialEq, Debug, Readable, Writable)]
enum Enum {
    A,
    B,
    C,
}

#[derive(PartialEq, Debug, Readable, Writable)]
struct Struct< 'a > {
    number: u64,
    string: String,
    vector: Vec< u8 >,
    cow: Cow< 'a, [i64] >,
    float: f32,
    enumeration: Enum
}

fn main() {
    let original = Struct {
        number: 0x12345678ABCDEF00,
        string: "A totally pointless string".to_owned(),
        vector: vec![ 1, 2, 3 ],
        cow: Cow::Borrowed( &[ 4, 5, 6 ] ),
        float: 3.1415,
        enumeration: Enum::C
    };

    let endian = Endianness::LittleEndian;
    let bytes = original.write_to_vec( endian ).unwrap();
    let deserialized: Struct =
        Struct::read_from_buffer( endian, &bytes ).unwrap();

    assert_eq!( original, deserialized );
}
