Enum wgpu::naga::PredeclaredType

pub enum PredeclaredType {
    AtomicCompareExchangeWeakResult(Scalar),
    ModfResult {
        size: Option<VectorSize>,
        width: u8,
    },
    FrexpResult {
        size: Option<VectorSize>,
        width: u8,

}

Available on wgpu_core or naga only.

Return types predeclared for the frexp, modf, and atomicCompareExchangeWeak built-in functions.

These cannot be spelled in WGSL source.

Stored in SpecialTypes::predeclared_types and created by Module::generate_predeclared_type.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for PredeclaredType

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<PredeclaredType, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest( u: Unstructured<'arbitrary> ) -> Result<PredeclaredType, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for PredeclaredType

fn clone(&self) -> PredeclaredType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredeclaredType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PredeclaredType

fn deserialize<__D>( __deserializer: __D ) -> Result<PredeclaredType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PredeclaredType

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

where __H: Hasher,

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 PredeclaredType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for PredeclaredType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
