Trait U8Packer 

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