Struct GpuShaderCache 

pub struct GpuShaderCache { /* private fields */ }

In-process GPU shader cache.

Implementations

impl GpuShaderCache

pub fn new(max_bytes: usize, max_entries: usize, policy: EvictionPolicy) -> Self

Create a new shader cache.

• max_bytes – evict when total payload exceeds this many bytes.
• max_entries – evict when the number of entries exceeds this.
• policy – which eviction strategy to use.

pub fn insert(&mut self, shader: CompiledShader)

Insert a compiled shader into the cache.

If the cache is full, one entry is evicted according to the current policy before the new entry is stored.

pub fn get(&mut self, version: &ShaderVersion) -> Option<&CompiledShader>

Retrieve a compiled shader by its version key.

Returns None if the shader is not cached.

pub fn contains(&self, version: &ShaderVersion) -> bool

Check whether a shader is present in the cache.

pub fn remove(&mut self, version: &ShaderVersion) -> Option<CompiledShader>

Remove a specific shader from the cache.

pub fn invalidate_backend(&mut self, backend: &str)

Remove all shaders for a given backend.

pub fn clear(&mut self)

Clear all entries.

pub fn stats(&self) -> &ShaderCacheStats

Current statistics.

pub fn len(&self) -> usize

Number of entries currently held.

pub fn is_empty(&self) -> bool

Returns true if the cache is empty.
