Trait U8Packer 

pub trait U8Packer {
    // Required methods
    fn pack_u8(first: u8, second: u8) -> Self;
    fn first_u8(&self) -> u8;
    fn second_u8(&self) -> u8;

    // Provided method
    fn unpack_u8(&self) -> (u8, u8) { ... }
}

Trait for packing and unpacking two u8 values into a single value.

Required Methods

fn pack_u8(first: u8, second: u8) -> Self

Packs two u8 values into a single value of the implementing type.

Example

use num_packer::U8Packer;
let packed = u16::pack_u8(200, 55);
assert_eq!(packed, (200 << 8) + 55);

fn first_u8(&self) -> u8

Gets the first u8 value from the packed representation.

Example

use num_packer::U8Packer;
let packed = u16::pack_u8(200, 55);
assert_eq!(packed.first_u8(), 200);

fn second_u8(&self) -> u8

Gets the second u8 value from the packed representation.

Example

use num_packer::U8Packer;
let packed = u16::pack_u8(200, 55);
assert_eq!(packed.second_u8(), 55);

Provided Methods

fn unpack_u8(&self) -> (u8, u8)

Unpacks the single value back into two u8 values.

Example

use num_packer::U8Packer;
let packed = u16::pack_u8(200, 55);
let (first, second) = packed.unpack_u8();
assert_eq!((first, second), (200, 55));

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
