//! Non-streaming chat completion.
//!
//! ```sh
//! cargo run --example chat_non_streaming
//! ```
//!
//! Requires `DEEPSEEK_API_KEY` in the environment. TLS: run with the
//! `ferritls` feature (`cargo run --features ferritls --example
//! chat_non_streaming`) or install your own rustls crypto provider — see
//! the crate docs ("TLS Crypto Provider").
