Description

Basic types useful everywhere we play with buffers.

Synopsis

Documentation

data Direction Source

Direction of movement inside a buffer

Constructors

Backward
Forward

Instances

Bounded Direction
Enum Direction
Eq Direction
Ord Direction
Show Direction
Generic Direction
Binary Direction
Typeable * Direction
type Rep Direction

reverseDir :: Direction -> Direction Source

mayReverse :: Direction -> [a] -> [a] Source

reverse if Backward

directionElim :: Direction -> a -> a -> a Source

direction is in the same style of maybe or either functions, It takes one argument per direction (backward, then forward) and a direction to select the output.
