Required Methods

fn allocate( &mut self, size: DeviceIntSize, texture_alloc_cb: &mut dyn FnMut(DeviceIntSize, &TextureParameters) -> CacheTextureId ) -> (CacheTextureId, AllocId, DeviceIntRect)

Allocate a rectangle.

If allocation fails, call the provided callback, add a new allocator to the list and try again.

fn set_handle( &mut self, texture_id: CacheTextureId, alloc_id: AllocId, handle: &TextureCacheHandle )

fn remove_handle(&mut self, texture_id: CacheTextureId, alloc_id: AllocId)

fn deallocate(&mut self, texture_id: CacheTextureId, alloc_id: AllocId)

Deallocate a rectangle and return its size.

fn texture_parameters(&self) -> &TextureParameters
