Correction parameter for predictor 2.

p3ca: u32

Correction parameters for predictor 3.

p3cb: u32

p3cc: u32

p3cd: u32

p3ce: u32

w0: u32

Weight multipliers for error weighting.

w1: u32

w2: u32

w3: u32

Implementations

impl WeightedPredictorParams

pub fn w(&self, i: usize) -> u32

Get weight multiplier by index.

pub fn is_default(&self) -> bool

Returns true if all parameters are at default values.

pub fn for_mode(mode: u8) -> Self

Get parameter set by mode index (0–4), matching libjxl’s PredictorMode().

• Mode 0: Default (lossless16)
• Mode 1: lossless8 variant
• Mode 2: West-biased lossless8
• Mode 3: North-biased lossless8
• Mode 4: Generic/balanced

Trait Implementations

impl Clone for WeightedPredictorParams

fn clone(&self) -> WeightedPredictorParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WeightedPredictorParams

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

Formats the value using the given formatter.

impl Default for WeightedPredictorParams

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for WeightedPredictorParams

fn eq(&self, other: &Self) -> 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.
