Thank you for taking the time to file a bug report. The following describes
some guidelines to creating a minimally useful ticket.

Above all else: do not describe your problem, SHOW your problem.

What version of the csv crate are you using?

https://docs.rs/csv/latest/csv/struct.Reader.html

Briefly describe the question, bug or feature request.

At docs.rs, there is a broken link on the Reader page (url above) in the text "For more details on the precise semantics of errors, see the Error type."

Maybe the Error type was changed from an Enum to a Struct at some point. And the docs need to be updated.
So https://docs.rs/csv/latest/csv/enum.Error.html should be https://docs.rs/csv/latest/csv/struct.Error.html instead.

Thanks
