Struct smoltcp::phy::Tracer

pub struct Tracer<D: for<'a> Device<'a>> { /* 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: for<'a> Device<'a>> 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<'a, D> Device<'a> for Tracer<D> where
    D: for<'b> Device<'b>, 

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

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

fn capabilities(&self) -> DeviceCapabilities

Get a description of device capabilities.

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

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

fn transmit(&'a mut self) -> Option<Self::TxToken>

Construct a transmit token.
