Struct Scalar

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

Characteristics of a scalar type.

Fields

kind: ScalarKind

How the value’s bits are to be interpreted.

width: Bytes

This size of the value in bytes.

Implementations

impl Scalar

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

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: Self

pub const U32: Self

pub const F32: Self

pub const F64: Self

pub const I64: Self

pub const BOOL: Self

pub const ABSTRACT_INT: Self

pub const ABSTRACT_FLOAT: Self

pub const fn float(width: Bytes) -> Self

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<'arbitrary> Arbitrary<'arbitrary> for Scalar

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

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

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

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.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

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

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Scalar

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Scalar

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 Scalar

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Scalar

impl Eq for Scalar
