Implementations

impl DerivedTraits

pub fn new(max_val: i32, near: i32, reset: i32) -> Self

pub fn quantize_error(&self, e: i32) -> i32

Quantize an error value for near-lossless mode.

pub fn mod_range(&self, err: i32) -> i32

Map an error value into the modular range.

pub fn compute_error_val(&self, e: i32) -> i32

Compute the error value: quantize then mod-range.

pub fn dequantize(&self, err: i32) -> i32

De-quantize an error value.

pub fn compute_reconstructed(&self, px: i32, err: i32) -> i32

Reconstruct the sample from prediction and error.

pub fn correct_prediction(&self, pxc: i32) -> i32

Clamp a predicted value to [0, MAXVAL].
