Trait BoolPacker 

pub trait BoolPacker {
    // Required methods
    fn pack_bool(first: bool, second: bool) -> Self;
    fn first_bool(&self) -> bool;
    fn second_bool(&self) -> bool;

    // Provided method
    fn unpack_bool(&self) -> (bool, bool) { ... }
}

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

Required Methods

fn pack_bool(first: bool, second: bool) -> Self

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

Example

use num_packer::BoolPacker;
let packed = u8::pack_bool(true, false);
assert_eq!(packed, 0b10);

fn first_bool(&self) -> bool

Gets the first bool value from the packed representation.

Example

use num_packer::BoolPacker;
let packed = u8::pack_bool(true, false);
assert_eq!(packed.first_bool(), true);

fn second_bool(&self) -> bool

Gets the second bool value from the packed representation.

Example

use num_packer::BoolPacker;
let packed = u8::pack_bool(true, false);
assert_eq!(packed.second_bool(), false);

Provided Methods

fn unpack_bool(&self) -> (bool, bool)

Unpacks the single value back into two bool values.

Example

use num_packer::BoolPacker;
let packed = u8::pack_bool(true, false);
let (first, second) = packed.unpack_bool();
assert_eq!((first, second), (true, false));

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.
