Trait SafeUnwrap

pub trait SafeUnwrap<T> {
    // Required methods
    fn safe_unwrap(&self) -> &T;
    fn safe_unwrap_mut(&mut self) -> &mut T;
}

Trait implemented to unwrap optional parse tree items initially introduced in hyperledger/solang#1068.

Note that the methods of this trait should only be used on parse tree items’ fields, like [pt::VariableDefinition] or [pt::EventDefinition], where the name field is None only when an error occurred during parsing.
