Enum RenderOutcome 

pub enum RenderOutcome {
    Presented,
    Skipped,
    NeedsReconfigure,
    DeviceLost,
}

What happened when Renderer::render tried to present a frame.

Variants

Presented

The frame was drawn and presented.

Skipped

The frame was skipped (occlusion, timeout, or a validation error); the caller should just try again on the next redraw.

NeedsReconfigure

The surface is lost or outdated: call Renderer::reconfigure before retrying.

DeviceLost

The GPU device is gone — a driver reset, a GPU removed or restarted: this renderer can draw nothing more, and a new one is to be made (milestone 686, #217).
