pub trait TryIntoIfSome<T> {
    // Required method
    fn try_into_if_some<S: ToString>(
        self,
        field: S,
    ) -> Result<T, TryFromProtoError>;
}

Convenience syntax for trying to convert a Self value of type Option<U> to T if the value is Some(value), or returning TryFromProtoError::MissingField if the value is None.
