addConstraintTCM :: Blocker -> Constraint -> TCM () Source #
wakeConstraintsTCM :: (ProblemConstraint -> WakeUp) -> TCM () Source #
stealConstraintsTCM :: ProblemId -> TCM () Source #
Add all constraints belonging to the given problem to the current problem(s).
noConstraints :: (MonadConstraint m, MonadWarning m, MonadError TCErr m, MonadFresh ProblemId m) => m a -> m a Source #
Don't allow the argument to produce any blocking constraints.
WARNING: this does not mean that the given computation cannot constrain the solution space further. It can well do so, by solving metas.
nonConstraining :: (HasOptions m, MonadConstraint m, MonadDebug m, MonadError TCErr m, MonadFresh ProblemId m, MonadTCEnv m, MonadWarning m) => m a -> m a Source #
Run a computation that should succeeds without constraining the solution space, i.e., not add any information about meta-variables.
newProblem :: (MonadFresh ProblemId m, MonadConstraint m) => m a -> m (ProblemId, a) Source #
Create a fresh problem for the given action.
newProblem_ :: (MonadFresh ProblemId m, MonadConstraint m) => m a -> m ProblemId Source #
guardConstraint :: Constraint -> TCM () -> TCM () Source #
guardConstraint c blocker tries to solve blocker first.
If successful without constraints, it moves on to solve c, otherwise it
adds a c to the constraint pool, blocked by the problem generated by blocker.
wakeConstraints' :: (ProblemConstraint -> WakeUp) -> TCM () Source #
Wake constraints matching the given predicate (and aren't instance
constraints if shouldPostponeInstanceSearch).
wakeupConstraints :: MetaId -> TCM () Source #
Wake up the constraints depending on the given meta.
wakeupConstraints_ :: TCM () Source #
Wake up all constraints not blocked on a problem.
solveAwakeConstraints :: MonadConstraint m => m () Source #
solveAwakeConstraints' :: MonadConstraint m => Bool -> m () Source #
solveSomeAwakeConstraintsTCM :: (ProblemConstraint -> Bool) -> Bool -> TCM () Source #
Solve awake constraints matching the predicate. If the second argument is
True solve constraints even if already isSolvingConstraints.
solveConstraintTCM :: Constraint -> TCM () Source #
solveConstraint_ :: Constraint -> TCM () Source #
debugConstraints :: TCM () Source #
