Struct WeightedPredictorState 

pub struct WeightedPredictorState { /* private fields */ }

Full weighted predictor state for adaptive prediction. Matches libjxl/jxl-rs implementation for encoding parity.

Implementations

impl WeightedPredictorState

pub fn new(params: &WeightedPredictorParams, xsize: usize) -> Self

Creates a new weighted predictor state.

pub fn with_defaults(xsize: usize) -> Self

Creates with default parameters.

pub fn predict_and_property( &mut self, x: usize, y: usize, xsize: usize, neighbors: &Neighbors, ) -> (i64, i32)

Compute prediction and property value. Returns (prediction, max_error_property).

pub fn update_errors(&mut self, actual: i32, x: usize, y: usize, xsize: usize)

Update error buffers after seeing actual value.

pub fn predict( &mut self, x: usize, y: usize, xsize: usize, neighbors: &Neighbors, ) -> i32

Simple predict method for compatibility.

Trait Implementations

impl Debug for WeightedPredictorState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for WeightedPredictorState

fn default() -> Self

Returns the “default value” for a type.
