Enum easy_repl::command::CriticalError

pub enum CriticalError {
    Critical(Error),
}

Special error wrapper used to indicate that a critical error occured.

Handler can return CriticalError to indicate that this error should not be handled by the REPL (which just prints error message and continues for all other errors).

This is most conveniently used via the Critical extension trait.

Variants

Critical(Error)

The contained error is critical and should be returned back from REPL.
