streamly Streamly.Prelude Map a Maybe returning function to a stream, filter out the Nothing elements, and return a stream of values extracted from Just. Equivalent to:
mapMaybe f = Stream.map fromJust . Stream.filter isJust . Stream.map f
mapMaybeM :: (IsStream t, MonadAsync m, Functor (t m)) => (a -> m (Maybe b)) -> t m a -> t m bstreamly Streamly.Prelude Like mapMaybe but maps a monadic function. Equivalent to:
mapMaybeM f = Stream.map fromJust . Stream.filter isJust . Stream.mapM f
Concurrent (do not use with fromParallel on infinite streams)mapMaybe :: (a -> Maybe b) -> [a] -> [b]strict-base-types Data.Maybe.Strict Analogous to mapMaybe in Data.Maybe.
maps :: StringPrepProfile -> [Map]stringprep Text.StringPrep No documentation available.
mapNumber :: (Double -> Double) -> Number -> Numbersvg-tree Graphics.Svg.CssTypes Helper function to modify inner value of a number
mapNumber :: (Double -> Double) -> Number -> Numbersvg-tree Graphics.Svg.Types Helper function to modify inner value of a number
mapTree :: (Tree -> Tree) -> Tree -> Treesvg-tree Graphics.Svg.Types Helper function mapping every tree element.
mapL2V :: DatatypeMap vt -> Text -> Maybe vtswish Swish.Datatype Function to map a lexical string to the datatype value. This effectively defines the lexical space of the datatype to be all strings for which yield a value other than Nothing.
mapV2L :: DatatypeMap vt -> vt -> Maybe Textswish Swish.Datatype Function to map a value to its canonical lexical form, if it has such.
mapLabelIndex :: Label lb => LabelMap lb -> lb -> LabelIndexswish Swish.GraphMatch Map a label to its corresponding label index value in the supplied LabelMap.
