Std.Ui.changes

fn

This is a callable function.

What it does

The changes that turn one screen into the other.

Both trees are walked together. A node whose element name changed is

replaced whole rather than reconciled, because an element that became a

different element shares nothing with what it was, and matching its children

anyway produces a tree that is wrong and renders plausibly.

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.
