O(1) length returns the length of a ByteString as an Int.
O(n/c) length returns the length of a ByteString as an Int64
Returns the size/length of a finite structure as an Int. The default implementation is optimized for structures that are similar to cons-lists, because there is no general way to do better.
Number of elements in NonEmpty list.
The number of elements in the sequence.
O(n) Returns the number of characters in a Text. Subject to fusion.
