Std.LinkedMap.touch

fn

This is a callable function.

What it does

The map with an entry moved to the end of the order, added if it is new.

The recency order insert deliberately does not keep. A cache deciding what

to discard, or a list of recently opened files, wants the key it just

touched to be last; both are asking a different question from "when did this

first appear", so both are spelled differently.

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.
