Enum ImageQuery

pub enum ImageQuery {
    Size {
        level: Option<Handle<Expression>>,
    },
    NumLevels,
    NumLayers,
    NumSamples,
}

Available on crate feature unstable-wgpu-24 only.

Type of an image query.

All Handle<Expression> values here refer to an expression in Function::expressions.

Variants

Size

Get the size at the specified level.

The return value is a u32 for 1D images, and a vecN<u32> for an image with dimensions N > 2.

Fields

level: Option<Handle<Expression>>

If None, the base level is considered.

NumLevels

Get the number of mipmap levels, a u32.

NumLayers

Get the number of array layers, a u32.

NumSamples

Get the number of samples, a u32.

Trait Implementations

impl Clone for ImageQuery

fn clone(&self) -> ImageQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageQuery

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

Formats the value using the given formatter.

impl PartialEq for ImageQuery

fn eq(&self, other: &ImageQuery) -> 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 Copy for ImageQuery

impl StructuralPartialEq for ImageQuery
