The unpacked representation type.

Required Methods§

Source

fn pack_pair(low: Self, high: Self) -> u8

Pack a low and high element into a single byte.

Source

fn unpack_pair(packed: u8) -> (Self, Self)

Unpack a single byte into a low and high element.

Source

fn unpack_slice_packed(packed: &[u8], unpacked: &mut [Self::Unpacked])

Unpack a slice of packed pairs to a slice of unpacked elements.

Source

fn unpack_single(element: Self) -> Self::Unpacked
