Struct PacketCapture 

pub struct PacketCapture { /* private fields */ }

Records all traffic in memory via WireTap.

Use drain to retrieve and clear the buffer. For bounded capture with automatic eviction, see RingBufferCapture.

Prefer BusCapture for new code — it includes built-in statistics counters.

Implementations

impl PacketCapture

pub fn new() -> Self

Create an empty packet capture buffer.

pub fn drain(&self) -> Vec<PacketRecord>

Retrieve and clear all captured records.

pub fn len(&self) -> usize

Number of recorded packets.

pub fn is_empty(&self) -> bool

Returns true if no packets have been recorded.

Trait Implementations

impl Default for PacketCapture

fn default() -> Self

Returns the “default value” for a type.

impl WireTap for PacketCapture

fn on_write(&self, bytes: &[u8], ts: u64)

Bytes successfully written to the transport. Called once per poll_write that returns Ok(n) with n > 0.

fn on_read(&self, bytes: &[u8], ts: u64)

Bytes successfully read from the transport. Called once per poll_read that returns Ready(Ok(())) with new data.

fn on_error(&self, bytes: &[u8], error: &str, ts: u64)

Read returned an error, but partial data may have been received. Called when poll_read returns Ready(Err(e)) and the read buffer contains bytes that arrived before the error.
