#NonEmptyArray Source

newtype NonEmptyArray a

An array that is known not to be empty.

You can use the constructor to create a NonEmptyArray that isn't non-empty, breaking the guarantee behind this newtype. It is provided as an escape hatch mainly for the Data.Array.NonEmpty and Data.Array modules. Use this at your own risk when you know what you are doing.
