1/// Uses the `log` crate to perform logging.
2/// This must be enabled using the feature flag `debug-print`.
3/// ### Usage
4/// ```
5/// use sea_orm::debug_print;
6///
7/// #[derive(Debug)]
8/// enum FooError {
9///     Bar,
10///     Baz,
11/// }
12///
13/// debug_print!("{:?}", FooError::Bar);
14/// ```
