Struct Extent3d

#[repr(C)]
pub struct Extent3d {
    pub width: u32,
    pub height: u32,
    pub depth_or_array_layers: u32,
}

Extent of a texture related operation.

Corresponds to WebGPU GPUExtent3D.

Fields

width: u32

Width of the extent

height: u32

Height of the extent

depth_or_array_layers: u32

The depth of the extent or the number of array layers

Implementations

impl Extent3d

pub fn physical_size(&self, format: TextureFormat) -> Extent3d

Calculates the physical size backing a texture of the given format and extent. This includes padding to the block width and height of the format.

This is the texture extent that you must upload at when uploading to mipmaps of compressed textures.

pub fn max_mips(&self, dim: TextureDimension) -> u32

Calculates the maximum possible count of mipmaps.

Treats the depth as part of the mipmaps. If calculating for a 2DArray texture, which does not mipmap depth, set depth to 1.

pub fn mip_level_size(&self, level: u32, dim: TextureDimension) -> Extent3d

Calculates the extent at a given mip level. Does not account for memory size being a multiple of block size.

Trait Implementations

impl Clone for Extent3d

fn clone(&self) -> Extent3d

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Extent3d

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

Formats the value using the given formatter.

impl Default for Extent3d

fn default() -> Extent3d

Returns the “default value” for a type.

impl Hash for Extent3d

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 Extent3d

fn eq(&self, other: &Extent3d) -> 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.
