Std.Ui.Layout.placeWithin

1 declaration

fn

placeWithin: &Std.Ui.Layout.View -> Std.Ui.Canvas.Size -> Int -> Int -> Result[Std.Ui.Layout.Layout, Std.Ui.Layout.LayoutError]

This is a callable function.

What it does

Place a view with explicit node and nesting budgets.

Two passes over the tree. The first measures every node's intrinsic size

bottom-up, once, independent of the space offered; the second gives each

node its frame top-down, resolving stretch and grow from the frame its

parent was given. No node is measured twice.

  • 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.
