Struct DefaultPerfRenderer 

pub struct DefaultPerfRenderer { /* private fields */ }

The built-in PerfRenderer, used by PerfOverlayApp::new.

A single-row NNNfps MM.Mms minMM.M maxMM.M <backend> readout, right-aligned within its area, on a solid background. Colored from a Theme (see DefaultPerfRenderer::theme), so a caller matching a Theme-driven UI elsewhere doesn’t get a hardcoded, unrelated palette here.

A no-op before the first frame is recorded, or if the readout doesn’t fit area’s width.
