Struct MonitorBuilder 

pub struct MonitorBuilder { /* private fields */ }

Available on crate feature monitor only.

Builder for a NetworkMonitor. Configure an optional URL filter, then call Self::start to spawn the correlator task.

Obtained via crate::Tab::monitor.

Implementations

impl MonitorBuilder

pub fn url_pattern(self, pattern: impl Into<UrlMatcher>) -> Self

Restrict emitted events to those whose URL matches pattern.

Accepts anything convertible into a UrlMatcher: a &str / String (substring match) or a regex::Regex. For HTTP exchanges the request URL is matched; for WebSocket / EventSource events the connection URL observed at open time is matched.

Examples

// Only surface requests whose URL contains "/api/".
let monitor = tab.monitor().url_pattern("/api/").start().await?;

pub async fn start(self) -> Result<NetworkMonitor>

Spawn the correlator task and return a live NetworkMonitor.

The task subscribes to the session’s raw CDP event stream and runs until the monitor is dropped or NetworkMonitor::stop is called.

Errors

Currently infallible, but returns crate::Result so future setup (e.g. an explicit Network.enable round-trip) can surface errors without an API break.
