Struct ShaderCache 

pub struct ShaderCache { /* private fields */ }

Shader compilation cache for JIT-compiled kernels

Caches compiled shaders by query signature to avoid recompilation. Thread-safe via Mutex for concurrent query execution.

Implementations

impl ShaderCache

pub fn new() -> Self

Create a new shader cache

pub fn get_or_insert( &self, key: &str, device: &Device, shader_source: &str, ) -> Arc<ShaderModule>

Get cached shader or insert new one

Arguments

• key - Query signature (e.g., "filter_gt_1000_sum")
• device - GPU device for shader compilation
• shader_source - WGSL shader source code

Returns

Arc reference to compiled shader module (either cached or newly compiled)

Panics

Panics if the cache mutex is poisoned (should never happen in normal operation)

pub fn stats(&self) -> (usize, usize)

Get cache statistics

Panics

Panics if the cache mutex is poisoned (should never happen in normal operation)

Trait Implementations

impl Default for ShaderCache

fn default() -> Self

Returns the “default value” for a type.
