Struct Hash 

pub struct Hash { /* private fields */ }

Hash-based dithering (default method).

Fast general-purpose RNG with uniform distribution. Uses integer hash mixing for speed. Good choice when you need consistent performance across all index values.

Implementations

impl Hash

pub fn new(seed: u32) -> Self

Trait Implementations

impl Clone for Hash

fn clone(&self) -> Hash

Returns a duplicate of the value.

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

Simple dither for values in a slice (parallel version).

fn dither_iter<T, I>( &self, values: I, min: T, one: T, dither_amplitude: T, ) -> Vec<T>

impl PartialEq for Hash

fn eq(&self, other: &Hash) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
