Description

Demonstrates the use of enumeration values during queries.

Synopsis

Documentation

data Day Source #

Days of the week. We make it symbolic using the mkSymbolicEnumeration splice.

Methods

sexprToVal :: SExpr -> Maybe Day Source #

type SDay = SBV Day Source #

The type synonym SDay is the symbolic variant of Day. (Similar to 'SInteger'/'Integer' and others.)

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]
