Std.Tree.postorder

fn

This is a callable function.

What it does

Every value, each node after its children, children in order.

The order a hierarchy has to be taken apart in: nothing is visited until

everything beneath it has been, which is what a total, a deletion, or a

dependency build needs.

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.
