Is your feature request related to a problem? Please describe.
i keep geting errors that error converting to string with no context as to why it couldent.

Describe the solution you'd like
instead of returning Result<&str, ()> return Result<&str, impl std::error::Error>

Describe alternatives you've considered
n/a

Additional context
i see from scrolling through the src code that its prob because my data is not of type String but ether way a error type of () is not acceptible.
