typeHashForNames :: [Name] -> Q Exp Source #
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

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
