Struct Controller

pub struct Controller<'a> { /* private fields */ }

A reference to the endpoint of layers below (phy + eth).

This is not really useful on its own but should instead be used either within a Packet or a RawPacket. Some of the methods offered there will access the non-public members of this struct to fulfill their task.

Implementations

impl<'a> Controller<'a>

pub fn borrow_mut(&mut self) -> Controller<'_>

Proof to the compiler that we can shorten the lifetime arbitrarily.

pub fn info(&self) -> &dyn Info

Get a reference to the network device information.

This is a central method since the ethernet layer abstracts over the phsical media in use. It splits the raw packet buffers supplied by the network device into a dynamic trait object with the device info (part of the handle) on one hand and the payload buffer on the other. This removes some detailed information on the device but simplifies layers on top.

pub fn src_addr(&mut self) -> Address

Get the configured (source) address of the ethernet endpoint.

pub fn send(&mut self) -> Result<()>

Try to send the packet associated with this controller.
