Std.BiMap.flipped

fn

This is a callable function.

What it does

The map with its two sides exchanged.

Free, because both directions are already held. This is the operation an

ordinary map cannot offer without rebuilding, and the reason to reach for

this type when a program reads a pairing both ways.

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.
