Struct Loopback

Source
pub struct Loopback<'r, C> { /* private fields */ }
Expand description

A software loop-back device.

Maintains a ring buffer of packet buffers in flight.

Implementations§

Source§

impl<'r, C: PayloadMut> Loopback<'r, C>

Source

pub fn new(buffer: Slice<'r, C>) -> Self

Create a loop-back device with mtu.

It will divide the packet buffer into chunks of the provided mtu and keep track of free and used buffers

Source

pub fn set_current_time(&mut self, instant: Instant)

Update the timestamp on all future received packets.
