Struct PacketRef

Source 
pub struct PacketRef<'a, M: RingMem> { /* private fields */ }
Expand description

A reference to a single packet that has not been read out of the ring yet.

Implementations§

Source§

impl<M: RingMem> PacketRef<'_, M>

Source

pub fn revert(&mut self)

Revert the read pointers, allowing a peek at the next packet.

Use this with care: a malicious guest could change the packet’s contents next time they are read. Any validation on the packet needs to be performed again next time the packet is read.

Trait Implementations§

Source§

impl<'a, M: RingMem> AsRef<IncomingPacket<'a, M>> for PacketRef<'a, M>

Source§

fn as_ref(&self) -> &IncomingPacket<'a, M>

Converts this type into a shared reference of the (usually inferred) input type.
Source§

impl<'a, M: RingMem> Deref for PacketRef<'a, M>

Source§

type Target = IncomingPacket<'a, M>

The resulting type after dereferencing.
Source§

fn deref(&self) -> &Self::Target
