Trait I8Packer 

pub trait I8Packer {
    // Required methods
    fn pack_i8(first: i8, second: i8) -> Self;
    fn first_i8(&self) -> i8;
    fn second_i8(&self) -> i8;

    // Provided method
    fn unpack_i8(&self) -> (i8, i8) { ... }
}

Trait for packing and unpacking two i8 values into a single value.

Required Methods

fn pack_i8(first: i8, second: i8) -> Self

Packs two i8 values into a single value of the implementing type.

Example

use num_packer::I8Packer;
let packed = u16::pack_i8(-100, 55);
assert_eq!(packed, ((-100i8 as u8 as u16) << 8) + (55u8 as u16));

fn first_i8(&self) -> i8

Gets the first i8 value from the packed representation.

Example

use num_packer::I8Packer;
let packed = u16::pack_i8(-100, 55);
assert_eq!(packed.first_i8(), -100);

fn second_i8(&self) -> i8

Gets the second i8 value from the packed representation.

Example

use num_packer::I8Packer;
let packed = u16::pack_i8(-100, 55);
assert_eq!(packed.second_i8(), 55);

Provided Methods

fn unpack_i8(&self) -> (i8, i8)

Unpacks the single value back into two i8 values.

Example

use num_packer::I8Packer;
let packed = u16::pack_i8(-100, 55);
let (first, second) = packed.unpack_i8();
assert_eq!((first, second), (-100, 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.
