//! The top-level [`IgClient`] — entry point for all REST domain APIs.
//!
//! Construction goes through [`IgClientBuilder`]:
//!
//! ```no_run
//! use trading_ig::{IgClient, Environment, Credentials};
//!
//! # async fn run() -> trading_ig::Result<()> {
//! let client = IgClient::builder()
//!     .environment(Environment::Demo)
//!     .api_key("YOUR_API_KEY")
//!     .credentials(Credentials::password("user", "pass"))
//!     .build()?;
//!
//! client.session().login().await?;
//! # Ok(()) }
