ByteImage

polydat_nodes::bytebuf

Struct ByteImage 

Source 
pub struct ByteImage { /* private fields */ }
Expand description

A pre-filled byte image for fast cycle-time extraction.

Built at init time by hash-filling a large buffer. At cycle time, a hash-based offset selects where to extract a variable-length slice. The extraction is just a memcpy — no per-byte computation.

Implementations§

Source§

impl ByteImage

Source

pub fn new(image_size: usize, seed: u64) -> Self

Build a byte image of image_size bytes from a seed.

Source

pub fn extract(&self, hash_val: u64, slice_size: usize) -> &[u8] ⓘ

Extract a slice at the given hash-based offset.
