sourcefn new(
color_formats: TextureFormatPair<ImageFormat>,
config: &TextureCacheConfig
) -> Self
fn new( color_formats: TextureFormatPair<ImageFormat>, config: &TextureCacheConfig ) -> Self
Mints a new set of shared textures.
sourcefn clear(&mut self, updates: &mut TextureUpdateList)
fn clear(&mut self, updates: &mut TextureUpdateList)
Clears each texture in the set, with the given set of pending updates.
sourcefn select(
&mut self,
external_format: ImageFormat,
filter: TextureFilter,
shader: TargetShader
) -> (&mut dyn AtlasAllocatorList<TextureParameters>, BudgetType)
fn select( &mut self, external_format: ImageFormat, filter: TextureFilter, shader: TargetShader ) -> (&mut dyn AtlasAllocatorList<TextureParameters>, BudgetType)
Returns a mutable borrow for the shared texture array matching the parameters.
How many bytes a single texture of the given type takes up, for the configured texture sizes.
