How to use it

From `examples/deep_analysis.rs`:

use infrastructure_browser_cdp::commands::runtime;
use infrastructure_browser_cdp::{BrowserEndpoint, DEFAULT_PORT};

fn main() {
    let ep = BrowserEndpoint::connect(&format!("http://localhost:{}", DEFAULT_PORT)).unwrap();
    let target = ep
        .find_target(|t| t.url.contains("whatsapp") && t.websocket_url.is_some())
        .unwrap()
        .expect("No WhatsApp tab");

    let session = ep.open_session(&target).unwrap();

    let deep_js = r#"(async function() {
        var report = {};

        var encrypted = 0, readable = 0, totalSize = 0;
        var suspiciousKeys = [];
        for (var i = 0; i < localStorage.length; i++) {

From `examples/read_chats.rs`:

use infrastructure_whatsapp_cdp::WhatsAppSession;

fn main() {
    let session = match WhatsAppSession::connect() {
        Ok(s) => s,
        Err(e) => {
            eprintln!("Failed to connect: {e}");
            std::process::exit(1);
        }
    };

    let probe = session.probe();
    println!("=== WhatsApp Web DOM Probe ===");
    println!("Sidebar: {:?}", probe.sidebar);
    println!("Compose: {:?}", probe.compose);
    println!("Messages: {:?}", probe.messages);
    println!("data-testid count: {}", probe.data_testids.len());
    println!();

Public surface

`probe`

Re-exports. Exported here, defined elsewhere.

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

1 workspace crate depends on this one: application-whatsapp-cdp.
