Struct TextureDescriptor 

pub struct TextureDescriptor {
    pub width: u32,
    pub height: u32,
    pub format: TextureFormat,
    pub mip_levels: u8,
    pub array_layers: u16,
}

Descriptor for a single GPU texture

Fields

width: u32

Width in texels

height: u32

Height in texels

format: TextureFormat

Texel format

mip_levels: u8

Number of mip levels (1 = base level only)

array_layers: u16

Number of array layers (1 = single texture)

Implementations

impl TextureDescriptor

pub fn new(width: u32, height: u32, format: TextureFormat) -> Self

Create a simple 2-D texture with no mip chain and a single layer

pub fn size_bytes(&self) -> usize

Total size in bytes for the full mip chain and all array layers

Each successive mip level has half the dimensions of the previous. Minimum mip size is 1×1.

pub fn total_pixels(&self) -> u64

Total number of texels in the base mip level (ignoring arrays / mips)

Trait Implementations

impl Clone for TextureDescriptor

fn clone(&self) -> TextureDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextureDescriptor

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

Formats the value using the given formatter.
