O(1) Extract the first element of a ByteString, which must be non-empty.

O(n/c) Extract the last element of a ByteString, which must be finite and non-empty.

O(1) Extract the elements after the head of a ByteString, which must be non-empty.

O(n/c) Return all the elements of a ByteString except the last one.

foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty ByteStrings.

'foldl1\'' is like foldl1, but strict in the accumulator.

foldr1 is a variant of foldr that has no starting value argument, and thus must be applied to non-empty ByteStrings

O(n) maximum returns the maximum value from a ByteString

O(n) minimum returns the minimum value from a ByteString
