Documentation

data SpanOrLoc

A SpanOrLoc consists of a start location and an end location

The end location must be greater than or equal to the start location; in other words, backwards spans are not permitted.

If the start and end location are the same, then the value is a SpanOrLoc. If they differ, then the value is a SpanOrLoc.

Constructing

span :: Span -> SpanOrLoc

loc :: Loc -> SpanOrLoc

fromTo :: Loc -> Loc -> SpanOrLoc

Construct a SpanOrLoc from two SpanOrLocs

If the two locs are not equal, the lesser loc will be the start, and the greater loc will be the end.
