Macro sqlx_error 

macro_rules! sqlx_error {
    () => { ... };
    ($desc:expr) => { ... };
}

The macro adds error path and optional description tosqlx::Error.

If you have a single sqlx query per function and the function path by itself provides enough context you can just use sqlx_error!(). If it’s not enough you can provide an additional message with sqlx_error!("more context").
