Enum MaternLengthScale 

pub enum MaternLengthScale {
    Auto {
        resolved: Option<f64>,
    },
    Fixed(f64),
}

User intent and resolved numeric state for a Matérn kernel length scale.

Auto remains auto-owned after the planner resolves its data-dependent numeric seed. This is deliberately not represented by a magic floating point value: callers can distinguish an omitted length_scale from an explicit value before and after center planning, and subsequent κ updates preserve that provenance.

Implementations

impl MaternLengthScale

pub const fn auto() -> Self

pub const fn fixed(value: f64) -> Self

pub const fn is_fixed(self) -> bool

pub const fn resolved(self) -> Option<f64>

pub fn set_resolved(&mut self, value: f64)

Install a numeric value without changing who owns the scale.

pub fn resolve_auto_once(&mut self, value: f64)

Resolve an omitted scale exactly once. Replanning a frozen or κ-updated Auto scale must retain its current numeric value.
