Trait Implementations

impl CpuBusProvider for Bus

fn read(&mut self, addr: u16) -> u8

each time the cpu reads, clock the components on the bus

fn write(&mut self, addr: u16, data: u8)

each time the cpu writes, clock the components on the bus

fn take_next_interrupt(&mut self) -> Option<InterruptType>

fn peek_next_interrupt(&mut self) -> Option<InterruptType>

fn is_hdma_running(&mut self) -> bool

fn enter_stop_mode(&mut self)

fn stopped(&self) -> bool

fn trigger_write_oam_bug(&mut self, addr: u16)

Triggers oam_bug without clock, this is used for inc/dec instructions

fn trigger_read_write_oam_bug(&mut self, addr: u16)

Triggers oam_bug special case read_write, this happens when an increment/decrement happen in the same cycle as read

fn read_no_oam_bug(&mut self, addr: u16) -> u8

reads data without triggering oam_bug, this is used in pop

impl Savable for Bus

fn save<W: Write>(&self, writer: &mut W) -> Result<()>

fn load<R: Read>(&mut self, reader: &mut R) -> Result<()>

fn save_size(&self) -> Result<u64>

The size of the object if saved now, note that this might change, for example due to the length of string objects or data inside the object.
