Enum ImageQuery

pub(super) enum ImageQuery {
    Size,
    SizeLevel,
    NumLevels,
    NumLayers,
    NumSamples,
}

HLSL backend requires its own ImageQuery enum.

It is used inside WrappedImageQuery and should be unique per ImageQuery function. IR version can’t be unique per function, because it’s store mipmap level as an expression.

For example:

let dim_cube_array_lod = textureDimensions(image_cube_array, 1);
let dim_cube_array_lod2 = textureDimensions(image_cube_array, 1);

ImageQuery {
 image: [1],
 query: Size {
     level: Some(
         [1],
     ),
 },
},
ImageQuery {
 image: [1],
 query: Size {
     level: Some(
         [2],
     ),
 },
},

HLSL should generate only 1 function for this case.

Trait Implementations

impl Clone for ImageQuery

fn clone(&self) -> ImageQuery

Returns a copy 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

Formats the value using the given formatter.

impl From<ImageQuery> for ImageQuery

fn from(q: ImageQuery) -> Self

Converts to this type from the input type.

impl Hash for ImageQuery

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 Ord for ImageQuery

fn cmp(&self, other: &ImageQuery) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for ImageQuery

fn partial_cmp(&self, other: &ImageQuery) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
