openai-auth 1.0.0

//! Basic OAuth flow with manual code entry (asynchronous)
//!
//! This example demonstrates the async API. Works with any async runtime
//! (tokio, async-std, smol, etc.). This example uses tokio.
//!
//! Required features: `async`
//!
//! Run with: cargo run --example 03_basic_manual_async
