Std.List.sortOn

1 declaration

fn

sortOn: &Array[T] -> fn(T) -> K -> Array[T] where K: Ord

This is a callable function.

What it does

The elements ordered by a key drawn from each one.

The key may be of any ordered type, not only a number: sorting people by

name is the same operation as sorting them by age.

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.
