Struct LutF64 

pub struct LutF64 { /* private fields */ }

A pre-computed interpolating lookup table mapping [0, 1] → f64.

Built at assembly time. Immutable and thread-safe after construction.

Implementations

impl LutF64

pub fn from_fn(f: impl Fn(f64) -> f64, resolution: usize) -> Self

Build from an arbitrary function over [0, 1].

f(p) is evaluated at resolution + 1 evenly spaced points from 0.0 to 1.0. Non-finite results are replaced with the nearest finite neighbor.

pub fn from_values(values: &[f64]) -> Self

Build from a pre-computed slice of values.

pub fn sample(&self, u: f64) -> f64

Query the LUT with linear interpolation.

u should be in [0.0, 1.0]. Values outside are clamped.

pub fn len(&self) -> usize

Number of precomputed points (resolution + 1).

pub fn is_empty(&self) -> bool

Whether the LUT has no precomputed points.

pub fn as_ptr(&self) -> *const f64

Raw pointer to the LUT data (for JIT constant baking).

pub fn resolution(&self) -> usize

The resolution (number of intervals).
