Std.List.sortBy
1 declaration
fn
sortBy: &Array[T] -> fn(T, T) -> Bool -> Array[T]This is a callable function.
What it does
The elements ordered by a comparison the caller supplies.
before answers whether its first argument sorts before its second; a
comparison that is not a total order produces an unspecified order rather
than a failure, which is the same promise every comparison sort makes.
