pub struct DirectMeasure<F>(pub F, pub u64);Expand description
The per-request form for in-process painters (gpui): one closure that
answers (leaf, wrap_width) with a size. None = unconstrained
(max-content); Some(0.0) = min-content. No baselines (see
DirectMeasureWithBaseline).

Identity of this measurer (font scale, Dynamic Type state…). Two
consecutive passes with different ids invalidate every memo.
