Trait that abstracts over different floppy controller implementations.

This trait allows re-using the same code for both the fully-featured floppy controller, and the stub floppy controller (which is required when booting via BIOS using the Microsoft PCAT firmware blob).

Required Associated Types

type NewError: Error + Send + Sync + 'static

Error type returned by new()

Required Methods

fn new( guest_memory: GuestMemory, interrupt: LineInterrupt, register_pio: &mut dyn RegisterPortIoIntercept, pio_base_addr: u16, disk_drive: DriveRibbon, dma: Box<dyn IsaDmaChannel>, ) -> Result<Self, Self::NewError>

Create a new FloppyDiskController

fn offset_of(&self, io_port: u16) -> Option<u16>

Return the offset of the given IO port, if it is handled by this device.

Object Safety

This trait is not object safe.
