3//! Langfuse SDK for Rust — LLM observability, prompt management, and evaluation.

5//! # Quick Start
6//! ```no_run
7//! use langfuse::Langfuse;
8//!
9//! let client = Langfuse::new(
10//!     langfuse_core::LangfuseConfig::builder()
11//!         .public_key("pk-lf-...")
12//!         .secret_key("sk-lf-...")
13//!         .build()
14//!         .unwrap()
15//! ).unwrap();
