I had a lot of trouble understanding this. Thus I am documenting it here for myself. All credit goes to the original StackOverFlow author. Add one of the following to the root of your crate.

Define a display trait for a struct or enum impl std::fmt::Display for MechanismError { fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result { match self { MechanismError::NotValidMechanismFormat(mesg) => { write!(f, "{} does not conform to any Mechanism format.", mesg) } MechanismError::NotIP4Network(mesg) => { write!(f, "Was given ip4:{}. This is not an ip4 network.", mesg) } MechanismError::NotIP6Network(mesg) => { write!(f, "Was given ip6:{}. This is not an ip6 network.", mesg) } MechanismError::NotValidIPNetwork(mesg) => { write!
