Description

ToGraphQL and FromGraphQL typeclasses used for user-defined type conversion.

Synopsis

class FromGraphQL a where
- fromGraphQL :: Value -> Maybe a
class ToGraphQL a where
- toGraphQL :: a -> Value

Documentation

class FromGraphQL a where Source #

Instances of this typeclass can be used to convert GraphQL internal representation to user-defined type.

Methods
