question: How can I convert mysql errors to HandlerError ? #549

Hey all, sorry in advance for putting a question in issues, but I'm having trouble converting error's from mysql crate to HandlerError was wondering if anyone could assist.

The mysql crate docs has this:

let pool = Pool::new(url)?;

I tried this with no luck:

let pool = Pool::new(url).map_err(|e| HandlerError::from(format!("{:?}", e).as_str()))?;

Any help is appreciated thanks!
