catchPatternErrTCM :: TCM a -> TCM a -> TCM a

addConstraintTCM :: Constraint -> TCM ()

wakeConstraintsTCM :: (ProblemConstraint -> TCM Bool) -> TCM ()

stealConstraintsTCM :: ProblemId -> TCM ()

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

Don't allow the argument to produce any blocking constraints.

newProblem :: (MonadFresh ProblemId m, MonadConstraint m) => m a -> m (ProblemId, a)

Create a fresh problem for the given action.

newProblem_ :: (MonadFresh ProblemId m, MonadConstraint m) => m a -> m ProblemId

ifNoConstraints :: TCM a -> (a -> TCM b) -> (ProblemId -> a -> TCM b) -> TCM b

ifNoConstraints_ :: TCM () -> TCM a -> (ProblemId -> TCM a) -> TCM a

guardConstraint :: Constraint -> TCM () -> TCM ()

guardConstraint c blocker tries to solve blocker first. If successful without constraints, it moves on to solve c, otherwise it adds a Guarded c cs constraint to the blocker-generated constraints cs.

whenConstraints :: TCM () -> TCM () -> TCM ()

wakeConstraints' :: (ProblemConstraint -> TCM Bool) -> TCM ()

Wake constraints matching the given predicate (and aren't instance constraints if shouldPostponeInstanceSearch).

wakeupConstraints :: MetaId -> TCM ()

Wake up the constraints depending on the given meta.

wakeupConstraints_ :: TCM ()

Wake up all constraints.

solveAwakeConstraints :: MonadConstraint m => m ()

solveAwakeConstraints' :: MonadConstraint m => Bool -> m ()

solveSomeAwakeConstraintsTCM :: (ProblemConstraint -> Bool) -> Bool -> TCM ()

Solve awake constraints matching the predicate. If the second argument is True solve constraints even if already isSolvingConstraints.
