lookupRegistered :: Text -> Registry -> Maybe SomeMessageTypeproto-lens Data.ProtoLens.Message Look up a message type by name (e.g., "type.googleapis.com/google.protobuf.FloatValue"). The URL corresponds to the field google.protobuf.Any.type_url.
lookupTypeNameWithLocals :: DsMonad q => String -> q (Maybe Name)th-desugar Language.Haskell.TH.Desugar Like lookupTypeName from Template Haskell, but looks also in Names of not-yet-typechecked declarations. To establish this list of not-yet-typechecked declarations, use withLocalDeclarations. Returns Nothing if no type with the same name can be found.
lookupValueNameWithLocals :: DsMonad q => String -> q (Maybe Name)th-desugar Language.Haskell.TH.Desugar Like lookupValueName from Template Haskell, but looks also in Names of not-yet-typechecked declarations. To establish this list of not-yet-typechecked declarations, use withLocalDeclarations. Returns Nothing if no value with the same name can be found.
