Struct PipelineFeatureFlags 

pub struct PipelineFeatureFlags(pub u32);

Capability bits that participate in pipeline-cache identity.

Two otherwise-identical pipelines compiled with different PipelineFeatureFlags produce different cache keys - a pipeline that assumed subgroup-op support cannot be reused on an adapter that does not expose subgroup ops even if the shader bytes match.

Encoded as a bitfield so the wire form is compact and trivially hashable. Bits 0x01..0x80 are allocated here; higher bits are reserved for additive backend capability flags.

Implementations

impl PipelineFeatureFlags

pub const SUBGROUP_OPS: Self

Pipeline was compiled against a lowering that emits subgroup / wave intrinsics.

pub const F16: Self

Pipeline was compiled with native f16 support.

pub const BF16: Self

Pipeline was compiled with native bf16 support.

pub const TENSOR_CORES: Self

Pipeline was compiled with tensor-core / matrix-engine intrinsics enabled.

pub const ASYNC_COMPUTE: Self

Pipeline expects an async-compute queue at dispatch time.

pub const PUSH_CONSTANTS: Self

Pipeline expects push-constant support at dispatch time.

pub const INDIRECT_DISPATCH: Self

Pipeline emits indirect-dispatch commands.

pub const SPECULATIVE: Self

Pipeline was compiled for speculative (fused prefilter+confirmer) dispatch.

pub const PERSISTENT_THREAD: Self

Pipeline was compiled for persistent-thread (device-side work queue) dispatch.

pub const fn empty() -> Self

Empty flag set.

pub const fn contains(self, other: Self) -> bool

Contains at least every bit of other.

pub const fn union(self, other: Self) -> Self

Union of two flag sets.

pub const fn bits(self) -> u32

Raw bit representation.

Trait Implementations

impl Clone for PipelineFeatureFlags

fn clone(&self) -> PipelineFeatureFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PipelineFeatureFlags

impl Debug for PipelineFeatureFlags

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

Formats the value using the given formatter.

impl Default for PipelineFeatureFlags

fn default() -> PipelineFeatureFlags

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PipelineFeatureFlags

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PipelineFeatureFlags

impl Hash for PipelineFeatureFlags

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 PipelineFeatureFlags

fn eq(&self, other: &PipelineFeatureFlags) -> 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.

impl Serialize for PipelineFeatureFlags

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
