Std.MultiMap.remove

fn

This is a callable function.

What it does

The map with one occurrence of a value removed from a key.

One occurrence, not all of them, because the values under a key are a bag:

removing every copy when the caller took one back would lose the others.

The key goes when its last value does.

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.
