Struct RecordingCaDevice 

pub struct RecordingCaDevice<D> {
    pub log: Vec<LinkEvent>,
    /* private fields */
}

A CaDevice decorator that records every frame in both directions (plus ioctls) for live-CAM diagnostics. Wrap a real device, run, then dump the log — or decode it with trace::decode_log — to get an annotated byte trace without hand-instrumenting the device:

let mut driver = Driver::new(RecordingCaDevice::new(real_device()));
driver.init().unwrap();
// ... pump ...
println!("{}", trace::decode_log(driver.device().log()));

Fields

log: Vec<LinkEvent>

The captured link events, in order.

Implementations

impl<D: CaDevice> RecordingCaDevice<D>

pub fn new(inner: D) -> Self

Wrap inner, recording all I/O.

pub fn log(&self) -> &[LinkEvent]

The recorded link events, in order.

pub fn inner(&self) -> &D

Borrow the wrapped device.

Trait Implementations

impl<D: CaDevice> CaDevice for RecordingCaDevice<D>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Read one link-layer TPDU frame into buf; returns the byte count. Ok(0) means no data available (non-blocking).

fn write(&mut self, buf: &[u8]) -> Result<()>

Write one link-layer TPDU frame.

fn reset(&mut self) -> Result<()>

Reset the interface / slot (ioctl CA_RESET).

fn slot_info(&mut self) -> Result<SlotInfo>

Query slot status (ioctl CA_GET_SLOT_INFO).

fn poll(&mut self, timeout: Duration) -> Result<bool>

Wait up to timeout for the device to become readable; Ok(true) if readable. The runtime’s poll loop calls this between reads.

impl<D: Debug> Debug for RecordingCaDevice<D>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D: Default> Default for RecordingCaDevice<D>

fn default() -> RecordingCaDevice<D>

Returns the “default value” for a type.
