Enum StorageTextureAccess

pub enum StorageTextureAccess {
    WriteOnly,
    ReadOnly,
    ReadWrite,
    Atomic,
}

Specific type of a sample in a texture binding.

For use in BindingType::StorageTexture.

Corresponds to WebGPU GPUStorageTextureAccess.

Variants

WriteOnly

The texture can only be written in the shader and it:

• may or may not be annotated with write (WGSL).
• must be annotated with writeonly (GLSL).

Example WGSL syntax:

@group(0) @binding(0)
var my_storage_image: texture_storage_2d<r32float, write>;

Example GLSL syntax:

layout(set=0, binding=0, r32f) writeonly uniform image2D myStorageImage;

ReadOnly

The texture can only be read in the shader and it must be annotated with read (WGSL) or readonly (GLSL).

Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES must be enabled to use this access mode. This is a native-only extension.

Example WGSL syntax:

@group(0) @binding(0)
var my_storage_image: texture_storage_2d<r32float, read>;

Example GLSL syntax:

layout(set=0, binding=0, r32f) readonly uniform image2D myStorageImage;

ReadWrite

The texture can be both read and written in the shader and must be annotated with read_write in WGSL.

Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES must be enabled to use this access mode. This is a nonstandard, native-only extension.

Example WGSL syntax:

@group(0) @binding(0)
var my_storage_image: texture_storage_2d<r32float, read_write>;

Example GLSL syntax:

layout(set=0, binding=0, r32f) uniform image2D myStorageImage;

Atomic

The texture can be both read and written in the shader via atomics and must be annotated with read_write in WGSL.

Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES must be enabled to use this access mode. This is a nonstandard, native-only extension.

Example WGSL syntax:

@group(0) @binding(0)
var my_storage_image: texture_storage_2d<r32uint, atomic>;

Trait Implementations

impl Clone for StorageTextureAccess

fn clone(&self) -> StorageTextureAccess

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageTextureAccess

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

Formats the value using the given formatter.

impl Hash for StorageTextureAccess

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 StorageTextureAccess

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