Passing a AnySetting to infect person

[erik-rosenstrom]

Ideally, we would want something like this in infection_attempt and infect_person but it results in an context immutability/mutability error

pub fn infection_attempt(context: &mut Context, person_id: PersonId) -> Option<PersonId> {
    if let Some(setting) = context.sample_setting(person_id) {
        let next_contact = context.get_contact(person_id, setting, ()).unwrap()?;
        match context.get_person_property(next_contact, InfectionStatus) {
            InfectionStatusValue::Susceptible => {
                if context.sample_bool(
                    ForecastRng,
                    context.get_relative_total_transmission(next_contact),
                ) {
                    context.infect_person(
                        next_contact,
                        Some(person_id),
                        Some(setting),
                    );
                    Some(next_contact)
                } else {
                    None
                }
            }
            _ => None,
        }
    } else {
        None
    }
}

fn infect_person(
        &mut self,
        target_id: PersonId,
        source_id: Option<PersonId>,
        setting: Option<&dyn AnySettingId>
    ) {
        let infection_time = self.get_current_time();
        trace!("Person {target_id}: Infected at {infection_time}");
        self.set_person_property(
            target_id,
            InfectionData,
            InfectionDataValue::Infectious {
                infection_time,
                infected_by: source_id,
                infection_setting_type: setting
                    .and_then(|s| Some(s.get_category_id())),
                infection_setting_id: setting.and_then(|s| Some(s.id()))
            },
        );
    }
