mkInterval

Methods

mkInterval :: StartPointOf interval -> EndPointOf interval -> interval Source #

Construct an interval given its start and end point.

pre: start < end

buildInterval :: StartPointOf interval -> EndPointOf interval -> interval Source #

Construct an interval given two points. This makes sure the start-point comes before the endpoint.

pre: it is possible to construct a valid, non-empty interval this way. so if either endpoint is open the endpoints should not coincide.
