  1. catchJust :: forall e b (es :: [Effect]) a . Exception e => (e -> Maybe b) -> Eff es a -> (b -> Eff es a) -> Eff es a

    effectful-core Effectful.Exception

    Lifted catchJust.

  2. handleJust :: forall e b (es :: [Effect]) a . (HasCallStack, Exception e) => (e -> Maybe b) -> (b -> Eff es a) -> Eff es a -> Eff es a

    effectful-core Effectful.Exception

    Flipped version of catchJust.

  3. tryJust :: forall e b (es :: [Effect]) a . Exception e => (e -> Maybe b) -> Eff es a -> Eff es (Either b a)

    effectful-core Effectful.Exception

    Lifted tryJust.

  4. showJustName :: Name -> String

    express Data.Express.Utils.TH

    Encodes a Name as a String. This is useful when generating error messages. 

    > showJustName ''Int
"Int"

    > showJustName ''String

    > showJustName ''Maybe
"Maybe"

  5. isJust :: Maybe a -> Bool

    foundation Foundation

    The isJust function returns True iff its argument is of the form Just _.

    Examples

    Basic usage: 
    >>> isJust (Just 3)
True

    >>> isJust (Just ())
True

    >>> isJust Nothing
False

    >>> isJust (Just Nothing)
True
