Struct VirtqueueBuffer

pub struct VirtqueueBuffer<'b> {
    pub buf: &'b mut [u8],
    pub len: usize,
    pub device_writeable: bool,
}

A slice of memory to be shared with a VirtIO device.

The VirtqueueBuffer allows to limit the portion of the passed slice to be shared with the device through the len field. Furthermore, the device can be asked to not write to the shared buffer by setting device_writeable to false.

The SplitVirtqueue does not actually enfore that a VirtIO device adheres to the device_writeable flag, although compliant devices should.
