Trait user_facing_errors::SimpleUserFacingError

pub trait SimpleUserFacingError {
    const ERROR_CODE: &'static str;
    const MESSAGE: &'static str;
}

A less dynamic type of user-facing errors. This is used in the introspection and migration engines for simpler, more robust and helpful error handling — extra details are attached opportunistically.
