[−][src]Struct webrender::api::ExternalScrollId
An external identifier that uniquely identifies a scroll frame independent of its ClipId, which may change from frame to frame. This should be unique within a pipeline. WebRender makes no attempt to ensure uniqueness. The zero value is reserved for use by the root scroll node of every pipeline, which always has an external id.
When setting display lists with the preserve_frame_state this id is used to preserve scroll
offsets between different sets of ClipScrollNodes which are ScrollFrames.
