pub struct Scalar {
    pub kind: ScalarKind,
    pub width: u8,
}
Available on wgpu_core or naga only.
Expand description

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§

source§

impl Scalar

source

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

Available on wgpu_core only.

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.

source

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

Available on wgpu_core only.

Return true if automatic conversions will covert self to goal.

source§

impl Scalar

source

pub fn to_wgsl(self) -> String

Available on wgpu_core only.

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

Examples: f32, u64, bool.

source

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

Available on wgpu_core only.

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