Trait Packer

pub trait Packer {
    // Required methods
    fn size(&self) -> usize;
    fn pack(&self, enc: &mut Encoder) -> usize;
    fn unpack(&mut self, data: &[u8]) -> usize;
}

The Packer trait provides methods for packing and unpacking values to and from byte arrays.

Examples

use crate::rust_chain::serializer::{Encoder, Decoder, Packer};

let mut encoder = Encoder::new(4);
let value = 123u32;
value.pack(&mut encoder);

let mut decoder = Decoder::new(&encoder.get_bytes());
let mut unpacked_value = 0u32;
decoder.unpack(&mut unpacked_value);

assert_eq!(value, unpacked_value);

Required Methods

fn size(&self) -> usize

Returns the size of the packed representation of this value in bytes.

fn pack(&self, enc: &mut Encoder) -> usize

Packs this value into the given Encoder.

Arguments

• enc - The encoder to pack this value into.

Returns

The number of bytes written to the encoder.

fn unpack(&mut self, data: &[u8]) -> usize

Unpacks this value from the given byte array.

Arguments

• data - The byte array to unpack this value from.

Returns

The number of bytes read from the byte array.
