Std.PrefixTrie.remove

fn

This is a callable function.

What it does

The trie with a key's value removed, or unchanged when it has none.

Nodes left holding nothing and leading nowhere are dropped on the way back

up, so removing a key gives back the path it did not share.

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.
