Struct CpuTexture 

pub struct CpuTexture {
    pub pixels: Vec<u8>,
    pub size: Extent3D,
    pub format: TextureFormat,
    pub mip_level_count: u32,
    pub sample_count: SampleCount,
    pub dimension: TextureDimension,
    pub usage: TextureUsage,
}

A CPU-side representation of a decoded texture, ready to be uploaded to the GPU.

Fields

pixels: Vec<u8>

The raw pixel data (e.g., in RGBA format)

size: Extent3D

The size of the texture

format: TextureFormat

The format of the pixel data

mip_level_count: u32

The number of mip levels

sample_count: SampleCount

The number of samples per pixel

dimension: TextureDimension

The dimensionality of the texture

usage: TextureUsage

The allowed usages for the future GPU texture

Implementations

impl CpuTexture

pub fn from_rgba32f(width: u32, height: u32, rgba: &[f32]) -> Option<CpuTexture>

Builds an HDR texture from linear f32 RGBA channels, packed to Rgba16Float.

rgba is row-major, 4 channels per pixel, and must hold exactly width * height * 4 values. Half-float keeps values above 1.0 (the point of HDR) while staying filterable on every backend, unlike 32-bit float. Use for procedurally generated HDR content — an environment map, a lookup table — that does not come from a decoded file.

Returns None if rgba’s length does not match width * height * 4.

pub fn to_descriptor<'a>( &self, label: Option<Cow<'a, str>>, ) -> TextureDescriptor<'a>

Creates a texture descriptor from this CPU texture data

pub fn row_size(&self) -> usize

Gets the row size in bytes (important for texture upload alignment)
