Struct SamplerCache 

pub struct SamplerCache { /* private fields */ }

In-memory cache that de-duplicates identical sampler configurations.

When the same SamplerConfig is requested more than once the same SamplerHandle is returned, avoiding redundant GPU object creation.

Example

use oximedia_gpu::sampler::{SamplerCache, SamplerConfig};

let mut cache = SamplerCache::new();
let h1 = cache.get_or_insert(SamplerConfig::linear_clamp());
let h2 = cache.get_or_insert(SamplerConfig::linear_clamp());
assert_eq!(h1, h2); // same config → same handle
assert_eq!(cache.len(), 1);

Implementations

impl SamplerCache

pub fn new() -> Self

Create an empty cache.

pub fn get_or_insert(&mut self, config: SamplerConfig) -> SamplerHandle

Return an existing handle if config is already cached, or allocate a new one and store it.

pub fn len(&self) -> usize

Number of unique sampler configurations in the cache.

pub fn is_empty(&self) -> bool

Return true if the cache contains no entries.

pub fn clear(&mut self)

Remove all cached entries and reset the handle counter.

Trait Implementations

impl Debug for SamplerCache

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

Formats the value using the given formatter.

impl Default for SamplerCache

fn default() -> SamplerCache

Returns the “default value” for a type.
