Variants

Void

Pseudo-type representing no data. It’s sometimes used to represent data without a type hint at compile-time in SPIR-V. You shouldn’t see this in your reflection results.

Boolean

Boolean value of either true or false. Be careful with booleans. Booleans is NOT allowed to be exposed to the host according to the SPIR-V specification. You shouldn’t see this in your reflection results.

Integer

Two’s complement integer.

Fields

bits: u32

Number of bytes the integer takes.

is_signed: bool

Whether the integer is signed.

Float

IEEE 754 floating-point number.

Fields

bits: u32

Number of bytes the float takes.

Implementations

impl ScalarType

pub fn int(bits: u32) -> ScalarType

Create a signed integer type with the given number of bits.

pub fn uint(bits: u32) -> ScalarType

Create an unsigned integer type with the given number of bits.

pub fn float(bits: u32) -> ScalarType

Create a floating point type with the given number of bits.

pub fn i32() -> ScalarType

Create a 32-bit signed integer type.

pub fn u32() -> ScalarType

Create a 32-bit unsigned integer type.

pub fn f32() -> ScalarType

Create a 32-bit floating-point type.

Trait Implementations

impl Clone for ScalarType

fn clone(&self) -> ScalarType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarType

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

Formats the value using the given formatter.

impl Display for ScalarType

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

Formats the value using the given formatter.

impl Hash for ScalarType

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 ScalarType

fn eq(&self, other: &ScalarType) -> 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 SpirvType for ScalarType

fn min_nbyte(&self) -> Option<usize>

Minimum size of the type in bytes if it can be represented in-memory. It’s the size of all static members and plus one element if it’s an array. Same as wgpu::BindingType::Buffer::min_binding_size.

fn nbyte(&self) -> Option<usize>

Size of the type in bytes if it can be represented in-memory.

fn is_sized(&self) -> bool

Returns true if the type is sized. A sized type can be represented in-memory. Otherwise the type can only be used as a descriptor resource.

fn member_offset(&self, _member_index: usize) -> Option<usize>

Returns the offset of the i-th member in bytes if it’s a composite type.

fn access_ty(&self) -> Option<AccessType>

Returns how the type can be accessed: ReadOnly, WriteOnly or ReadWrite.
