Drafter.RenderCache (drafter v0.3.1)

Process-dictionary cache for incremental rendering.

Tracks per-widget strip fingerprints and the last composited output so the renderer can skip recompositing rows where nothing changed.

Summary

Absolute screen rows that changed between two per-row cache-key lists.

get_composited()

invalidate()

@spec changed_rows([term()] | nil, [term()], non_neg_integer()) ::
  MapSet.t(non_neg_integer())

Absolute screen rows that changed between two per-row cache-key lists.

bounds_y offsets the row index to a screen row. A nil previous list (the widget's first frame) marks every row dirty.
