Trait U32Packer 

pub trait U32Packer {
    // Required methods
    fn pack_u32(first: u32, second: u32) -> Self;
    fn first_u32(&self) -> u32;
    fn second_u32(&self) -> u32;

    // Provided method
    fn unpack_u32(&self) -> (u32, u32) { ... }
}

Trait for packing and unpacking two u32 values into a single value.

Required Methods

fn pack_u32(first: u32, second: u32) -> Self

Packs two u32 values into a single value of the implementing type.

Example

use num_packer::U32Packer;
let packed = u64::pack_u32(200, 55);
assert_eq!(packed, (200u64 << 32) + 55);

fn first_u32(&self) -> u32

Gets the first u32 value from the packed representation.

Example

use num_packer::U32Packer;
let packed = u64::pack_u32(200, 55);
assert_eq!(packed.first_u32(), 200);

fn second_u32(&self) -> u32

Gets the second u32 value from the packed representation.

Example

use num_packer::U32Packer;
let packed = u64::pack_u32(200, 55);
assert_eq!(packed.second_u32(), 55);
`

Provided Methods

fn unpack_u32(&self) -> (u32, u32)

Unpacks the single value back into two u32 values.

Example

use num_packer::U32Packer;
let packed = u64::pack_u32(200, 55);
let (first, second) = packed.unpack_u32();
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.
