Struct Tracer

pub struct Tracer<D: Device> { /* private fields */ }

A tracer device.

A tracer is a device that pretty prints all packets traversing it using the provided writer function, and then passes them to another device.

Implementations

impl<D: Device> Tracer<D>

pub fn new( inner: D, writer: fn(timestamp: Instant, packet: Packet<'_>), ) -> Tracer<D>

Create a tracer device.

pub fn get_ref(&self) -> &D

Get a reference to the underlying device.

Even if the device offers reading through a standard reference, it is inadvisable to directly read from the device as doing so will circumvent the tracing.

pub fn get_mut(&mut self) -> &mut D

Get a mutable reference to the underlying device.

It is inadvisable to directly read from the device as doing so will circumvent the tracing.

pub fn into_inner(self) -> D

Return the underlying device, consuming the tracer.

Trait Implementations

impl<D: Device> Device for Tracer<D>

type RxToken<'a> = RxToken<<D as Device>::RxToken<'a>> where Self: 'a

type TxToken<'a> = TxToken<<D as Device>::TxToken<'a>> where Self: 'a

fn capabilities(&self) -> DeviceCapabilities

Get a description of device capabilities.

fn receive( &mut self, timestamp: Instant, ) -> Option<(Self::RxToken<'_>, Self::TxToken<'_>)>

Construct a token pair consisting of one receive token and one transmit token.

fn transmit(&mut self, timestamp: Instant) -> Option<Self::TxToken<'_>>

Construct a transmit token.
