Struct PipelineCacheKey 

pub struct PipelineCacheKey {
    pub shader_key: ShaderKey,
    pub workgroup_size: [u32; 3],
    pub push_constant_bytes: u32,
    pub layout_hash: u64,
}

Composite key for a GPU pipeline cache entry.

Uniquely identifies a compiled pipeline based on the shader variant and pipeline parameters.

Fields

shader_key: ShaderKey

Shader variant key.

workgroup_size: [u32; 3]

Workgroup size.

push_constant_bytes: u32

Push constant size in bytes.

layout_hash: u64

Bind group layout signature (e.g. a hash of the layout).

Implementations

impl PipelineCacheKey

pub fn new( shader_key: ShaderKey, workgroup_size: [u32; 3], push_constant_bytes: u32, layout_hash: u64, ) -> Self

Create a new cache key.

pub fn hash_key(&self) -> u64

Compute an FNV-1a hash of the entire key.

Trait Implementations

impl Clone for PipelineCacheKey

fn clone(&self) -> PipelineCacheKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PipelineCacheKey

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

Formats the value using the given formatter.

impl Hash for PipelineCacheKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PipelineCacheKey

fn eq(&self, other: &PipelineCacheKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
