a dynamic field
updateLookupable :: Lookup a => a -> DTree -> Either String a Source
Update something using a dynamic representation
describeDField :: DField -> String Source
sameDFieldType :: DField -> DField -> Bool Source
Returns True if the type of fields is the same.
some utility functions for working with DSimpleEnums
denumToString :: DSimpleEnum -> Either String String Source
Get the constructor string or an error message.
denumToStringOrMsg :: DSimpleEnum -> String Source
Get the constructor string or an error message without telling which is which.
denumSetString :: DSimpleEnum -> String -> Either String DSimpleEnum Source
Try to update an enum with its constructor. Fail if not a valid constructor.
denumSetIndex :: DSimpleEnum -> Int -> Either String DSimpleEnum Source
Try to update an enum with its index. Fail if out of bounds.
