Description
This module provides compatibility definitions of destructuring result type of reify for before temaplate-haskell-2.11
- unClassOpI :: Info -> Maybe (Name, Type, ParentName)
- unDataConI :: Info -> Maybe (Name, Type, ParentName)
- unVarI :: Info -> Maybe (Name, Type, Maybe Dec)
- reifyFixity :: Name -> Q (Maybe Fixity)
- type ParentName = Name
Interfaces to destruct reify result
unClassOpI :: Info -> Maybe (Name, Type, ParentName) #
Compatible interface to destruct ClassOpI
unDataConI :: Info -> Maybe (Name, Type, ParentName) #
Compatible interface to destruct DataConI
Interface to get operator fixity
reifyFixity :: Name -> Q (Maybe Fixity) #
reifyFixity nm attempts to find a fixity declaration for nm. For
example, if the function foo has the fixity declaration infixr 7 foo, then
reifyFixity 'foo would return Just (Fixity 7 InfixR)bar does not have a fixity declaration, then reifyFixity 'bar returns
Nothing, so you may assume bar has defaultFixity.
Interface of type alias name
type ParentName = Name #
