Struct Texture 

pub struct Texture { /* private fields */ }

A 2D texture asset — from_file/from_data/empty, then chained with_* calls, then build_asset. An empty() texture can be used as a render target (post-processing, shadow maps).

Implementations

impl Texture

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

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

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

No source data — a render target, or something you’ll write yourself.

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

pub fn with_mips(self) -> Self

Generates a full GPU-side mip chain.

pub fn with_mip_count(self, count: u32) -> Self

Generates exactly count mip levels, rather than a full chain — e.g. for a PBR prefilter pass.

pub fn build_asset( self, name: &str, assets: &mut Assets<Texture>, ) -> Handle<Texture>

pub fn data(&self) -> Option<&[u8]>

CPU-side pixels, e.g. for heightmap sampling. Only ever Some for a from_data() texture — from_file() re-decodes from disk on each upload rather than keeping a copy around.

pub fn release_cpu_data(&mut self)

Frees the CPU-side copy of a from_data() texture once you’re done reading it via data. Any future re-upload (e.g. after GPU backend loss) then produces an empty texture instead of the original contents. No-op for from_file()/empty().
