Struct GridConfig

pub struct GridConfig {
    pub x_min: f64,
    pub x_max: f64,
    pub n_points: usize,
    pub x_transition: f64,
    pub log_fraction: f64,
    pub refinement_zones: Vec<RefinementZone>,
}

Configuration for the frequency grid.

Presets Self::fast (500 points) and Self::production (4000 points) cover the common cases. Hand-rolled configurations must satisfy Self::validate: in particular, x_max ≥ 30 for accurate G₃ integrals.

Fields

x_min: f64

Lower grid bound in dimensionless frequency x = hν/(kT_z). Must be positive (log spacing). Default 1e-4.

x_max: f64

Upper grid bound. Must be ≥ 30 for accurate spectral integrals.

n_points: usize

Total number of grid points.

x_transition: f64

Transition frequency from log to linear spacing.

log_fraction: f64

Fraction of points allocated to the log region (must be in [0, 1)).

refinement_zones: Vec<RefinementZone>

Optional refinement zones for extra resolution near injection features.

Implementations

impl GridConfig

pub fn production() -> Self

Production-quality grid: 4000 points, x ∈ [1e-5, 60]. Used for all paper runs.

pub fn fast() -> Self

Fast/testing grid: 500 points, x ∈ [1e-4, 40]. Suitable for quick exploratory runs; distortion amplitudes are accurate to a few percent.

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

Validate grid configuration parameters.

Returns Err with a descriptive message if any parameter would cause numerical failure or produce meaningless results.

pub fn with_refinement(self, zone: RefinementZone) -> Self

Add a refinement zone to this grid configuration.

Trait Implementations

impl Clone for GridConfig

fn clone(&self) -> GridConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GridConfig

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

Formats the value using the given formatter.

impl Default for GridConfig

fn default() -> Self

Returns the “default value” for a type.
