1//! # Intent Classification Library
2//!
3//! A flexible few-shot intent classification library for natural language processing.
4//! This library provides a simple API for classifying user intents from text using
5//! machine learning and rule-based approaches.
6//!
7//! ## Features
8//!
9//! - **Few-shot learning**: Train the classifier with minimal examples
10//! - **Bootstrap data**: Comes with pre-trained examples for common intents
11//! - **Feedback learning**: Improve accuracy through user feedback
12//! - **Async support**: Fully async API for non-blocking operations
13//! - **Serializable**: Export/import training data as JSON
14//! - **Configurable**: Customize behavior through configuration
15//!
16//! ## Quick Start
17//!
18//! ```rust
19//! use intent_classifier::{IntentClassifier, TrainingExample, TrainingSource, IntentId};
20//!
21//! #[tokio::main]
22//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
23//!     // Create a new classifier
24//!     let classifier = IntentClassifier::new().await?;
25//!
26//!     // Predict an intent
27//!     let prediction = classifier.predict_intent("merge these JSON files together").await?;
28//!     println!("Intent: {}, Confidence: {:.3}", 
29//!              prediction.intent, prediction.confidence.value());
30//!
31//!     // Add custom training data
32//!     let example = TrainingExample {
33//!         text: "calculate the sum of these numbers".to_string(),
34//!         intent: IntentId::from("math_operation"),
35//!         confidence: 1.0,
36//!         source: TrainingSource::Programmatic,
37//!     };
38//!     classifier.add_training_example(example).await?;
39//!
40//!     // Get statistics
41//!     let stats = classifier.get_stats().await;
42//!     println!("Training examples: {}", stats.training_examples);
43//!
44//!     Ok(())
45//! }
46//! ```
47//!
