BitSparrow in Rust

Encoding

use bitsparrow::Encoder;

let buffer = Encoder::new()
             .uint8(100)
             .string("Foo")
             .end();

assert_eq!(buffer, &[0x64,0x03,0x46,0x6f,0x6f])

Each method on the Encoder will return a mutable borrow of the encoder. If you need to break the monad chain, store the owned encoder as a variable before writing to it, e.g.:

use bitsparrow::Encoder;

let mut encoder = Encoder::new();
encoder.uint8(100);

/*
 * Many codes here
 */

let buffer = encoder.string("Foo").end();

assert_eq!(buffer, &[0x64_u8,0x03,0x46,0x6f,0x6f]);

Decoding

use bitsparrow::Decoder;

let buffer = &[0x64,0x03,0x46,0x6f,0x6f];
let mut decoder = Decoder::new(buffer);

assert_eq!(100u8, decoder.uint8().unwrap());
assert_eq!("Foo", decoder.string().unwrap());
assert_eq!(true, decoder.end());

Decoder allows you to retrieve the values in order they were encoded. Calling the end method is optional - it will return true if you have read the entire buffer, ensuring the entire buffer has been read.

Structs

Decoder	Decoder reads from a binary slice buffer (`&[u8]`) and exposes methods to read BitSparrow types from it in the same order they were encoded by the `Encoder`.
Encoder	Encoder takes in typed data and produces a binary buffer represented as `Vec<u8>`.

Enums

Error

Simple error type returned either by the Decoder or Encoder
