Std.MultiMap.inverted

fn

This is a callable function.

What it does

The map with its keys and values exchanged.

Each value becomes a key holding every key it appeared under, which is the

reverse index a caller otherwise builds by hand.

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.
