Std.List.subsequences

fn

This is a callable function.

What it does

Every subsequence, including the empty one and the whole array.

The count doubles with each element, so this is for small inputs by nature

rather than by choice.

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.
