Struct wgpu::core::naga::Scalar

pub struct Scalar {
    pub kind: ScalarKind,
    pub width: u8,
}

Characteristics of a scalar type.

Fields

kind: ScalarKind

How the value’s bits are to be interpreted.

width: u8

This size of the value in bytes.

Implementations

impl Scalar

pub const fn automatic_conversion_combine(self, other: Scalar) -> Option<Scalar>

Find the common type of self and other under WGSL’s automatic conversions.

If there are any scalars to which WGSL’s automatic conversions will convert both self and other, return the best such scalar. Otherwise, return None.

pub fn automatically_converts_to(self, goal: Scalar) -> bool

Return true if automatic conversions will covert self to goal.

impl Scalar

pub fn to_wgsl(self) -> String

Format a scalar kind+width as a type is written in wgsl.

Examples: f32, u64, bool.

impl Scalar

pub const I32: Scalar = _

pub const U32: Scalar = _

pub const F32: Scalar = _

pub const F64: Scalar = _

pub const I64: Scalar = _

pub const BOOL: Scalar = _

pub const ABSTRACT_INT: Scalar = _

pub const ABSTRACT_FLOAT: Scalar = _

pub const fn is_abstract(self) -> bool

pub const fn float(width: u8) -> Scalar

Construct a float Scalar with the given width.

This is especially common when dealing with TypeInner::Matrix, where the scalar kind is implicit.

pub const fn to_inner_scalar(self) -> TypeInner

pub const fn to_inner_vector(self, size: VectorSize) -> TypeInner

pub const fn to_inner_atomic(self) -> TypeInner

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl Hash for Scalar

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 Scalar

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