catchConstraint :: Constraint -> TCM () -> TCM ()

Catches pattern violation errors and adds a constraint.

addConstraint :: Constraint -> TCM ()

noConstraints :: TCM a -> TCM a

Don't allow the argument to produce any constraints.

newProblem :: TCM a -> TCM (ProblemId, a)

Create a fresh problem for the given action.

newProblem_ :: TCM () -> TCM 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 cs c tries to solve constraints cs first. If successful, it moves on to solve c, otherwise it returns a Guarded c cs.

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

wakeupConstraints :: MetaId -> TCM ()

Wake up the constraints depending on the given meta.

wakeupConstraints_ :: TCM ()

Wake up all constraints.

solveAwakeConstraints :: TCM ()

solveConstraint :: Constraint -> TCM ()

solveConstraint_ :: Constraint -> TCM ()

localState :: MonadState s m => m a -> m a
