Struct CdpClient 

pub struct CdpClient { /* private fields */ }

Chrome DevTools Protocol client.

Connects to a browser via WebSocket and provides access to CDP commands and events.

let cdp = cdp_use::CdpClient::connect("ws://127.0.0.1:9222/devtools/browser/...").await?;
let result = cdp.send_raw("Target.getTargets", serde_json::json!({}), None).await?;
cdp.close().await?;

Implementations

impl CdpClient

pub async fn connect(url: &str) -> Result<Self, CdpError>

Connect to a CDP endpoint via WebSocket with default configuration.

pub async fn connect_with_config( url: &str, config: CdpClientConfig, ) -> Result<Self, CdpError>

Connect to a CDP endpoint via WebSocket with custom configuration.

use cdp_use::{CdpClient, CdpClientConfig};
use std::time::Duration;

let config = CdpClientConfig {
    command_timeout: Duration::from_secs(60),
    ..Default::default()
};
let cdp = CdpClient::connect_with_config("ws://127.0.0.1:9222/devtools/browser/...", config).await?;

pub async fn send_raw( &self, method: &str, params: Value, session_id: Option<&str>, ) -> Result<Value, CdpError>

Send a raw CDP command and await the response.

Returns CdpError::ConnectionClosed if the connection is already closed, or CdpError::Timeout if the browser does not respond within the timeout.

pub async fn emit_event( &self, method: &str, params: Value, session_id: Option<&str>, ) -> bool

Emit a synthetic event through the event registry.

Useful for custom domains where events are produced by application code rather than the browser.

pub async fn close(&self) -> Result<(), CdpError>

Gracefully close the WebSocket connection.

impl CdpClient

pub fn send(&self) -> CdpLibrary

Get domain clients for sending CDP commands.

let cdp = cdp_use::CdpClient::connect("ws://127.0.0.1:9222/devtools/browser/...").await?;
let send = cdp.send();
let targets = send.target.get_targets(Default::default(), None).await?;

impl CdpClient

pub fn register(&self) -> CdpRegistrationLibrary

Get domain registrations for subscribing to CDP events.

Trait Implementations

impl Clone for CdpClient

fn clone(&self) -> CdpClient

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
