viewpoint-core 0.4.3

//! Basic navigation example demonstrating `Viewpoint`'s browser automation.
//!
//! This example launches a headless Chromium browser, navigates to a URL,
//! and demonstrates different wait states.
//!
//! # Running
//!
//! Make sure Chromium is installed and accessible, then run:
//!
//! ```sh
//! cargo run --example basic_navigation
//! ```
