reifyManyTyDecls :: ((Name, Info) -> Q (Bool, [Name])) -> [Name] -> Q [(Name, Info)] #

typeHashForNames :: [Name] -> Q Exp #

At compiletime, this yields a hash of the specified datatypes. Not only does this cover the datatypes themselves, but also all transitive dependencies.

The resulting expression is a literal of type TypeHash.

hashOfType :: Type -> Q Exp #

At compiletime, this yields a cryptographic hash of the specified Type, including the definition of things it references (transitively).

The resulting expression is a literal of type TypeHash.

Deprecated: Use of Data.Store.TypeHash isn't recommended, as the hashes are too unstable for most uses. Please instead consider using Data.Store.Version. See https://github.com/fpco/store/issues/53
