Struct SurfaceConditionNoiseCache 

pub struct SurfaceConditionNoiseCache<'a> {
    values: &'a [Cell<f64>],
    initialized: &'a [Cell<bool>],
}

Lazily caches x/z-only surface condition noise values for one column.

Fields

values: &'a [Cell<f64>]

initialized: &'a [Cell<bool>]

Implementations

impl<'a> SurfaceConditionNoiseCache<'a>

pub fn new(values: &'a [Cell<f64>], initialized: &'a [Cell<bool>]) -> Self

Creates a cache backed by caller-owned reusable storage.

pub fn reset(&self)

Clears populated markers before reusing the cache for another column.

pub fn get( &self, noise_index: usize, system: &dyn SurfaceNoiseProvider, x: i32, z: i32, ) -> f64

Returns a cached noise value, computing it if this column has not used it yet.
