Struct TextureDescriptor 

pub struct TextureDescriptor {
    pub file: Option<&'static str>,
    pub width: u32,
    pub height: u32,
    pub format: TextureFormat,
    pub data: Option<Vec<u8>>,
    pub generate_mips: bool,
}

Source data for GPUTexture, loaded from a file or supplied as raw bytes. Prefer the from_file/from_data constructors over setting fields by hand.

Fields

file: Option<&'static str>

File to decode — width/height are inferred from the image. Takes priority over data if both are set.

width: u32

Width in pixels. Ignored when loading from file.

height: u32

Height in pixels. Ignored when loading from file.

format: TextureFormat

GPU pixel format to upload as. Defaults to Rgba8UnormSrgb.

data: Option<Vec<u8>>

Raw pixel bytes, used when file is None.

generate_mips: bool

Whether to generate a full mip chain (via MipmapGenerator).

Implementations

impl TextureDescriptor

pub fn from_file(path: &'static str) -> Self

Load pixel data from a file. Width/height are inferred from the decoded image.

pub fn from_data( width: u32, height: u32, format: TextureFormat, data: Vec<u8>, ) -> Self

Supply raw pixel bytes directly, matching width/height/format.

pub fn with_format(self, format: TextureFormat) -> Self

pub fn with_mips(self) -> Self
