Expand description

The tax regime applied to a faction’s subjects.

Fields§

§faction: FactionId§flat_rate: f64

Flat tax rate applied to all income (0.0 – 1.0).

§brackets: Vec<(f64, f64)>

Progressive brackets: (threshold, marginal_rate).

§trade_tax_rate: f64

Percentage of trade route income taxed.

§import_duty: f64

Import duty (applied to value of goods arriving from other factions).

§export_duty: f64

Export duty.

§luxury_multiplier: f64

Luxury tax multiplier (applied to items tagged as luxury in markets).

§evasion_rate: f64

Tax evasion estimate (fraction that slips through).

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
