#[repr(C)]
pub struct VirtQueue<T>where
    T: Deref<Target = [VirtQueueEntry]>,{ /* private fields */ }

A container for holding virtqueue.

Implementations

impl VirtQueue<Box<[VirtQueueEntry]>>

pub fn new(size: usize) -> Self

pub fn virt_queue_ptr(&self) -> usize

Get a virtual address of the virtqueue.

impl VirtQueue<&'static [VirtQueueEntry]>

pub unsafe fn new_from_raw_ptr(size: usize, queue_va: Va) -> Self

Get a virtqueue from Va.

impl<T> VirtQueue<T>where T: Deref<Target = [VirtQueueEntry]>,

pub fn fetcher<'a>( &'a mut self, mmio: &'a mut VirtIoMmioHeader ) -> VirtQueueFetcher<'_, T>
