Std.Ui.Layout.paint

1 declaration

fn

paint: &Std.Ui.Layout.Layout -> &Std.Ui.Canvas.Canvas -> Result[Std.Ui.Canvas.Canvas, Std.Ui.Layout.LayoutError]

This is a callable function.

What it does

A canvas holding every node's fill and text, in painting order.

A node's fill covers its frame; its text starts at the top left of its

padded content and is not clipped to the frame, so text wider than a fixed

frame stays visible and its extent is what damage reports. Both are cut to

the window of every scrolling ancestor.

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.
  • Result makes success and recoverable failure part of the function's type.
