Struct LatticeCache 

pub struct LatticeCache { /* private fields */ }

Thread-safe cache for Pythagorean lattices.

Uses Arc<RwLock> for safe concurrent access. The cache automatically evicts old entries when capacity is reached.

Implementations

impl LatticeCache

pub fn new(capacity: usize) -> Self

Create a new lattice cache with specified capacity.

Arguments

• capacity - Maximum number of lattices to cache

Example

use constraint_theory_core::cache::LatticeCache;

let cache = LatticeCache::new(10);

pub fn with_default_capacity() -> Self

Create a cache with default capacity (32 lattices).

pub fn get_or_compute(&self, density: usize) -> CachedLattice

Get a cached lattice or compute and cache it.

Arguments

• density - Lattice density parameter

Returns

Reference to the cached lattice

Example

use constraint_theory_core::cache::LatticeCache;

let cache = LatticeCache::new(10);
let lattice = cache.get_or_compute(100);

assert!(lattice.len() > 0);

pub fn contains(&self, density: usize) -> bool

Check if a density is cached.

pub fn len(&self) -> usize

Get the number of cached lattices.

pub fn is_empty(&self) -> bool

Check if the cache is empty.

pub fn clear(&self)

Clear the cache.

pub fn precompute(&self, densities: &[usize])

Precompute and cache lattices for common densities.

Arguments

• densities - Slice of density values to precompute

Example

use constraint_theory_core::cache::LatticeCache;

let cache = LatticeCache::new(10);
cache.precompute(&[50, 100, 200]);

assert!(cache.contains(50));
assert!(cache.contains(100));
assert!(cache.contains(200));
