Enum RoundedBitWidth 

#[repr(u8)]
pub enum RoundedBitWidth {
    Zero = 0,
    Bits8 = 8,
    Bits16 = 16,
    Bits32 = 32,
}

Rounded bit width type for SIMD-friendly encoding

Variants

Zero = 0

Bits8 = 8

Bits16 = 16

Bits32 = 32

Implementations

impl RoundedBitWidth

pub fn from_exact(bits: u8) -> Self

Round an exact bit width to the nearest SIMD-friendly width

pub fn try_from_u8(bits: u8) -> Option<Self>

Convert from a stored u8 value; None unless it is exactly 0, 8, 16, or 32. Readers of persisted headers must use this and surface None as corruption instead of guessing a width.

pub fn from_u8(bits: u8) -> Self

Convert from a stored u8 value that has already been validated to be 0, 8, 16, or 32 (see Self::try_from_u8). Any other value maps to Bits32, which is only acceptable after the header has been checked.

pub fn bytes_per_value(self) -> usize

Get the byte size per value

pub fn as_u8(self) -> u8

Get the raw bit width value

Trait Implementations

impl Clone for RoundedBitWidth

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Copy for RoundedBitWidth

impl Debug for RoundedBitWidth

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

Formats the value using the given formatter.

impl Eq for RoundedBitWidth
