currentProblem :: TCM ProblemId

Get the current problem

stealConstraints :: ProblemId -> TCM ()

Steal all constraints belonging to the given problem and add them to the current problem.

solvingProblem :: ProblemId -> TCM a -> TCM a

solvingProblems :: [ProblemId] -> TCM a -> TCM a

isProblemSolved :: ProblemId -> TCM Bool

getConstraintsForProblem :: ProblemId -> TCM Constraints

getAwakeConstraints :: TCM Constraints

Get the awake constraints

showsPrec :: Int -> ConstraintStatus -> ShowS

show :: ConstraintStatus -> String

showList :: [ConstraintStatus] -> ShowS

holdConstraints :: (ConstraintStatus -> ProblemConstraint -> Bool) -> TCM a -> TCM a

Suspend constraints matching the predicate during the execution of the second argument. Caution: held sleeping constraints will not be woken up by events that would normally trigger a wakeup call.

getAllConstraints :: TCM Constraints

withConstraint :: (Constraint -> TCM a) -> ProblemConstraint -> TCM a

buildProblemConstraint :: ProblemId -> Constraint -> TCM ProblemConstraint

buildConstraint :: Constraint -> TCM ProblemConstraint

addConstraint' :: Constraint -> TCM ()

Add new a constraint

addAwakeConstraints :: Constraints -> TCM ()

Add already awake constraints

nowSolvingConstraints :: TCM a -> TCM a

Start solving constraints
