pub fn new( keyboard_col: Rc<Cell<u8>>, mapping_strategy: KeyMappingStrategy, platform: Arc<dyn PlatformProvider> ) -> Self

Create a new instance of the port, with the given keyboard column, reading the key status from the given platform.

Trait Implementations

impl Port for VicVia2PortA

fn read(&mut self) -> u8

Read a byte from the port. This is implementation-defined, and may have side effects.

fn write(&mut self, _value: u8)

Write a byte to the port. This is implementation-defined.

fn poll(&mut self, _cycles_since_poll: u64, _total_cycle_count: u64) -> bool

Poll the port for interrupts. A port may trigger an interrupt for any implementation-defined reason.

fn reset(&mut self)

Reset the port to its initial state, analogous to a system reboot.
