alt :: Alternative f => (a -> a -> a) -> f a -> f a -> f a

Functions like an Applicative but keeps the Just value if it exists.

andMaybe :: [Maybe Bool] -> Maybe Bool

Returns the and of the Just values or Nothing if there are no Justs

computeMaximumConstraints :: [Maybe Scientific] -> [Maybe Bool] -> (Maybe Scientific, Maybe Bool)

The unification function for the integer constraints maximum and exclusiveMaximum. When unifying schemas the exclusiveMaximum may somestimes need to be modified based on the @maximum.

computeMinimumConstraints :: [Maybe Scientific] -> [Maybe Bool] -> (Maybe Scientific, Maybe Bool)

The unification function for the integer constraints minimum and exclusiveMinimum. When unifying schemas the exclusiveMinimum may somestimes need to be modified based on the @minimum.

zipWithPadding :: a -> b -> [a] -> [b] -> [(a, b)]

Zips a list but uses the default value if one list is longer than the other.

listToMaybeList :: [a] -> Maybe [a]

Similar to listFromMaybe, but returns the entire list as a Just if it is not empty instead of only the first item.

setToMaybeSet :: Set a -> Maybe (Set a)

Returns the entire set as a Just if it is not empty instead of only one item.

parseValue :: ByteString -> Value

Parses a bytestring to a value.

printSchema :: Schema -> Text

Converts a schema to text.
