Struct webrender::renderer::TextureResolver

struct TextureResolver {
    texture_cache_map: FastHashMap<CacheTextureId, CacheTexture>,
    external_images: FastHashMap<DeferredResolveIndex, ExternalTexture>,
    dummy_cache_texture: Texture,
}

Helper struct for resolving device Textures for use during rendering passes.

Manages the mapping between the at-a-distance texture handles used by the RenderBackend (which does not directly interface with the GPU) and actual device texture handles.

Fields

texture_cache_map: FastHashMap<CacheTextureId, CacheTexture>

A map to resolve texture cache IDs to native textures.

external_images: FastHashMap<DeferredResolveIndex, ExternalTexture>

Map of external image IDs to native textures.

dummy_cache_texture: Texture

A special 1x1 dummy texture used for shaders that expect to work with the output of the previous pass but are actually running in the first pass.
