Description

Demonstrates the use of enumeration values during queries.

Methods

parseCVs :: [CV] -> Maybe (Day, [CV]) Source #

cvtModel :: (Day -> Maybe b) -> Maybe (Day, [CV]) -> Maybe (b, [CV]) Source #

type SDay = SBV Day Source #

Make Day a symbolic value.

findDays :: IO [Day] Source #

A trivial query to find three consecutive days that's all before Thursday. The point here is that we can perform queries on such enumerated values and use getValue on them and return their values from queries just like any other value. We have:

>>> findDays
[Monday,Tuesday,Wednesday]
