last

Extract the last element of a list, which must be finite and non-empty.

>>> last [1, 2, 3]
3

>>> last [1..]
* Hangs forever *

>>> last []
*** Exception: Prelude.last: empty list

WARNING: This function is partial. You can use reverse with case-matching, uncons or listToMaybe instead.

The last element of a non-empty structure.

>>> last (1 :| [2, 3, 4])

Extract the last element of the stream.

O(1) Extract the last element of a ByteString, which must be finite and non-empty. An exception will be thrown in the case of an empty ByteString. This is a partial function, consider using unsnoc instead.

O(1) Extract the last element of a packed string, which must be non-empty.

O(n/c) Extract the last element of a ByteString, which must be finite and non-empty. This is a partial function, consider using unsnoc instead.

O(1) Extract the last element of a ShortByteString, which must be finite and non-empty. An exception will be thrown in the case of an empty ShortByteString. This is a partial function, consider using unsnoc instead.

O(1) Returns the last character of a Text, which must be non-empty. This is a partial function, consider using unsnoc instead.

O(n) Returns the last character of a Stream Char, which must be non-empty. Properties

O(n/c) Returns the last character of a Text, which must be non-empty. This is a partial function, consider using unsnoc instead.

O(1) Extract the last element of a ShortByteString, which must be finite and at least one Word16. An exception will be thrown in the case of an empty ShortByteString.
