Struct Descriptor 

pub struct Descriptor {
    pub addr: GuestAddress,
    pub len: u32,
    pub flags: u16,
    pub next: u16,
}

One descriptor entry from a chain: a single guest buffer with its flags.

Fields

addr: GuestAddress

Guest-physical address of the buffer.

len: u32

Buffer length in bytes.

flags: u16

VIRTQ_DESC_F_* flags.

next: u16

Next descriptor index (only valid if flags & NEXT).

Implementations

impl Descriptor

pub fn is_write_only(&self) -> bool

true if the device should treat this buffer as device-write (it fills the buffer) rather than device-read (it consumes the buffer).

pub fn has_next(&self) -> bool

true if a successor descriptor exists.
