Struct GeometryCache 

pub struct GeometryCache<V> { /* private fields */ }

A geometry instance cache for deduplication.

Caches shared geometry data to avoid duplicating vertex arrays when the same geometry appears multiple times.

Implementations

impl<V: Clone> GeometryCache<V>

pub fn new() -> Self

Creates a new empty cache.

pub fn get_or_insert(&mut self, id: &str, vertices: Vec<V>) -> SharedGeometry<V>

Gets or creates a shared geometry.

If a geometry with the same ID exists, returns a shared reference. Otherwise, creates a new entry with the provided vertices.

pub fn contains(&self, id: &str) -> bool

Checks if a geometry is already cached.

pub fn len(&self) -> usize

Returns the number of cached geometries.

pub fn is_empty(&self) -> bool

Returns true if the cache is empty.

pub fn clear(&mut self)

Clears the cache.

pub fn memory_usage(&self) -> usize

Returns total memory usage estimate (vertex count * size).

Trait Implementations

impl<V: Default> Default for GeometryCache<V>

fn default() -> GeometryCache<V>

Returns the “default value” for a type.
