Std.Ui.Layout.damage

fn

This is a callable function.

What it does

The regions whose pixels differ between two placements of a screen.

A node that changed what it paints damages where it was and where it is,

measured by its extent: its frame, grown to cover text overflowing it. A

change of structure or viewport damages everything, because node positions

no longer correspond. Repainting only these regions of the earlier surface

gives exactly the surface a full render of the later layout gives.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
