Struct PolynomialChannel 

pub struct PolynomialChannel {
    pub kind: ChannelKind,
    pub scale_exponent: u8,
    pub coefficients: Vec<f64>,
}

Quantized polynomial coefficients for one channel of a time segment.

Fields

kind: ChannelKind

Channel kind.

scale_exponent: u8

Decimal scale exponent used when quantizing coefficients.

coefficients: Vec<f64>

Polynomial coefficients in ascending power order, expressed in native channel units.

Implementations

impl PolynomialChannel

pub fn new( kind: ChannelKind, scale_exponent: u8, coefficients: Vec<f64>, ) -> Self

Creates a channel from already-normalized polynomial coefficients.

pub fn linear( kind: ChannelKind, scale_exponent: u8, start: f64, end: f64, ) -> Self

Creates a linear channel from endpoint values over the normalized interval [0, 1].

pub fn quadratic( kind: ChannelKind, scale_exponent: u8, start: f64, midpoint: f64, end: f64, midpoint_x: f64, ) -> Self

Creates a quadratic channel that interpolates start, midpoint, and end values over the normalized interval [0, 1].

pub fn validate(&self) -> Result<(), CompressionError>

Validates that the channel coefficients are finite before encoding or lookup.
