Struct NfpCache 

pub struct NfpCache { /* private fields */ }

Thread-safe NFP cache for storing precomputed NFPs.

Implementations

impl NfpCache

pub fn new() -> Self

Creates a new NFP cache with default capacity (1000 entries).

pub fn with_capacity(max_size: usize) -> Self

Creates a new NFP cache with specified capacity.

pub fn get_or_compute<F>( &self, key: (&str, &str, f64), compute: F, ) -> Result<Arc<Nfp>>

where F: FnOnce() -> Result<Nfp>,

Gets a cached NFP or computes and caches it.

Arguments

• key - Tuple of (geometry_id_a, geometry_id_b, rotation_in_radians)
• compute - Function to compute the NFP if not cached

pub fn get_or_compute_mirrored<F>( &self, key: (&str, &str, f64, bool, bool), compute: F, ) -> Result<Arc<Nfp>>

where F: FnOnce() -> Result<Nfp>,

Same as Self::get_or_compute, but the key also carries each side’s mirror state (allow_flip support) so a mirrored and an unmirrored NFP for the same (ids, rotation) don’t collide.

Arguments

• key - Tuple of (geometry_id_a, geometry_id_b, rotation_in_radians, mirror_a, mirror_b)

pub fn len(&self) -> usize

Returns the number of cached entries.

pub fn is_empty(&self) -> bool

Returns true if the cache is empty.

pub fn clear(&self)

Clears the cache.

Trait Implementations

impl Debug for NfpCache

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

Formats the value using the given formatter.

impl Default for NfpCache

fn default() -> Self

Returns the “default value” for a type.
