Struct SessionRecorder 

pub struct SessionRecorder { /* private fields */ }

Records CDP events and network traffic during a browser session.

Create one per scraping job, call record_event for each CDP event you want to log, then call stop and export_har when the session ends.

Implementations

impl SessionRecorder

pub fn start(config: RecorderConfig) -> Self

Start a new recorder with the given config.

pub fn is_running(&self) -> bool

Returns true if the recorder is currently running.

pub fn stop(&self)

Stop the recorder. No more events will be buffered after this.

pub fn record_event(&self, method: &str, params: Value)

Record a raw CDP event by method name and parameters.

Call this for every CDP event you receive from the browser. The recorder automatically tracks Network.requestWillBeSent and Network.responseReceived events to build HAR entries.

pub fn export_event_log(&self, path: impl AsRef<Path>) -> Result<()>

Export the buffered CDP event log as a newline-delimited JSON file.

Errors

Returns an IO error if the file cannot be written.

pub fn export_har(&self, path: impl AsRef<Path>) -> Result<()>

Export captured network transactions as a HAR 1.2 file.

Errors

Returns an IO or serialisation error if the file cannot be written.

pub fn event_count(&self) -> usize

Return the number of buffered CDP events.

pub fn network_entry_count(&self) -> usize

Return the number of completed network entries.
