Trait Implementations

impl BlockDim for U4

const SHIFT: usize = 2usize

Number of left shifts of 1 for value.

const WIDTH: usize = _

Width and height of 2D block.

const AREA: usize = _

Number of elements in 2D block.

const MASK: usize = _

Bitmask for value.

fn round_up_to_valid(rows: usize, cols: usize) -> (usize, usize)

Rounds up dimensions to next valid size. Returns (rows, cols).

impl Clone for U4

fn clone(&self) -> U4

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for U4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for U4

fn eq(&self, other: &U4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
