litellm-rs 0.4.16

//! Python LiteLLM compatible completion API
//!
//! This module provides a Python LiteLLM-style API for making completion requests.
//! It serves as the main entry point for the library, providing a unified interface
//! to call 100+ LLM APIs using OpenAI format.
//!
//! # Example
//! ```rust,no_run
//! # use litellm_rs::{completion, user_message, system_message};
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let response = completion(
//!     "gpt-4",
//!     vec![
//!         system_message("You are helpful."),
//!         user_message("Hello!"),
//!     ],
//!     None,
//! ).await?;
//! # Ok(())
//! # }
//! ```
