Arguments

:: Alternative f
=> Int	The row of the position, where 0 is the row labelled 1.
-> Int	The column of the position, where 0 is the column labelled A.
-> f Position	The position, if it is within the bounds of the chess board.

Creates a position from row and column indices.

Arguments

:: Int	The row of the position, where 0 is the row labelled 1.
-> Int	The column of the position, where 0 is the column labelled A.
-> Position	The position, where out-of-bounds indices are limited to the valid range.

Creates a position from row and column indices.

Manipulating Positions

Arguments

:: Alternative f
=> Direction	The offset to be added to the position.
-> Position	The original position.
-> f Position	The new position, if it is within the bounds of the chess board.

Adds an offset to a position, yielding a new position.

Arguments

:: Direction	The offset to be added to the position.
-> Position	The original position.
-> Position	The new position, where out-of-bounds indices are limited to the valid range.

Adds an offset to a position, yielding a new position.
