Function uwuifier::uwuify_sse

pub fn uwuify_sse<'a>(
    bytes: &[u8], 
    temp_bytes1: &'a mut [u8], 
    temp_bytes2: &'a mut [u8]
) -> &'a [u8]

uwuify some bytes

requires the sse4.1 x86 feature

temp_bytes1 and temp_bytes2 must be buffers of size round_up16(bytes.len()) * 16, because this is the worst-case size of the output. yes, it is annoying to allocate by hand, but simd :)

the returned slice is the uwu’d result. when working with utf-8 strings, just pass in the string as raw bytes and convert the output slice back to a string afterwards. there’s also the uwuify_str_sse function that is suitable for one-off use with a string slice

example:

use uwuifier::{uwuify_sse, round_up16};
let s = "hello world";
let b = s.as_bytes();
let mut temp1 = vec![0u8; round_up16(b.len()) * 16];
let mut temp2 = vec![0u8; round_up16(b.len()) * 16];
let res = uwuify_sse(b, &mut temp1, &mut temp2);
assert_eq!(std::str::from_utf8(res).unwrap(), "hewwo wowwd");
