maybeKey :: Key -> Decoder a -> Decoder (Maybe a)aeson-combinators Data.Aeson.Combinators.Decode Same as key but works with omitted attributes in payloads and produces parsed values in the context of Maybe. Note that this combinator behaves differently to a combination of maybe and key, which produce error if the attribute is missing from the json object. >>> decode (maybeKey "data" int) "{}" Just Nothing
maybeDecoder :: Decoder r -> Maybe rbinary-parsers Data.Binary.Parser Convert a Decoder value to a Maybe value. A Partial result is treated as failure. Since: 0.2.3.0
maybeKey :: String -> Maybe String -> Querybodhi Fedora.Bodhi Maybe create a query key
maybeL :: Lens' a (Maybe b) -> Maybe b -> a -> acabal-debian Debian.Debianize.Prelude If the current value of view x is Nothing, replace it with f.
maybeLens :: a -> Lens' a b -> Lens' (Maybe a) bcabal-debian Debian.Debianize.Prelude No documentation available.
maybeRead :: Read a => String -> Maybe acabal-debian Debian.Debianize.Prelude No documentation available.
maybeDecompress :: ByteString -> ByteStringcabal-install Distribution.Client.GZipUtils Attempts to decompress the bytes under the assumption that "data format" error at the very beginning of the stream means that it is already decompressed. Caller should make sanity checks to verify that it is not, in fact, garbage. This is to deal with http proxies that lie to us and transparently decompress without removing the content-encoding header. See: https://github.com/haskell/cabal/issues/678
maybeRepoRemote :: Repo -> Maybe RemoteRepocabal-install Distribution.Client.Types.Repo Extract RemoteRepo from Repo if remote.
maybeColor :: Handle -> [SGR] -> String -> IO Stringcabal2nix Distribution.Nixpkgs.Color If the given Handle should be colored, wrap a String in SGR codes.
maybeSubstTm :: HasCallStack => Doc () -> Maybe Subst -> Term -> Termclash-lib Clash.Core.Subst Substitute within a Term. Just return original term if given substitution is Nothing.
