Struct block_aligner::scan_block::PaddedBytes

pub struct PaddedBytes { /* fields omitted */ }

A padded string that helps avoid out of bounds access when using SIMD.

A single padding byte in inserted before the start of the string, and block_size bytes are inserted after the end of the string.

Implementations

impl PaddedBytes

pub fn from_bytes<M: Matrix>(b: &[u8], block_size: usize) -> Self

Create from a byte slice.

Make sure that block_size is greater than or equal to the upper bound block size used in the Block::align function.

pub fn from_str<M: Matrix>(s: &str, block_size: usize) -> Self

Create from the bytes in a string slice.

Make sure that block_size is greater than or equal to the upper bound block size used in the Block::align function.

pub fn from_string<M: Matrix>(s: String, block_size: usize) -> Self

Create from the bytes in a string.

Make sure that block_size is greater than or equal to the upper bound block size used in the Block::align function.

pub unsafe fn get(&self, i: usize) -> u8

Get the byte at a certain index (unchecked).

pub unsafe fn set(&mut self, i: usize, c: u8)

Set the byte at a certain index (unchecked).

pub unsafe fn as_ptr(&self, i: usize) -> *const u8

Create a pointer to a specific index.

pub fn len(&self) -> usize

Length of the original string (no padding).
