Struct ByteSliced2x128x1b

pub struct ByteSliced2x128x1b { /* private fields */ }

Implementations

impl ByteSliced2x128x1b

pub const BYTES: usize = 256usize

pub unsafe fn get_byte_unchecked(&self, byte_index: usize) -> u8

Get the byte at the given index.

Safety

The caller must ensure that byte_index is less than BYTES.

pub fn transpose_to( &self, out: &mut [PackedType<<PackedBinaryField128x1b as WithUnderlier>::Underlier, BinaryField1b>; 2], )

Convert the byte-sliced field to an array of “ordinary” packed fields preserving the order of scalars.
