1//! # rsigma-runtime
2//!
3//! Streaming runtime for rsigma — event sources, sinks, and log processing pipeline.
4//!
5//! This crate extracts the streaming pipeline from the `rsigma` CLI daemon into
6//! a reusable library. It provides:
7//!
8//! - **I/O adapters**: [`io::EventSource`] trait for inputs (stdin, NATS) and
9//!   [`io::Sink`] enum for outputs (stdout, file, NATS).
10//! - **Engine wrapper**: [`RuntimeEngine`] wraps `rsigma-eval`'s `Engine` and
11//!   `CorrelationEngine` with rule loading and state management.
12//! - **Log processor**: [`LogProcessor`] combines engine + metrics + event
13//!   filtering into a batch processing pipeline with atomic hot-reload via
14//!   `ArcSwap`.
15//! - **Metrics abstraction**: [`MetricsHook`] trait lets consumers plug in
16//!   Prometheus, OpenTelemetry, or any other metrics backend without the
17//!   runtime depending on a specific implementation.
18//!
19//! # Example
20//!
21//! ```rust,no_run
22//! use std::sync::Arc;
23//! use rsigma_runtime::{LogProcessor, RuntimeEngine, NoopMetrics};
24//! use rsigma_eval::CorrelationConfig;
25//!
26//! let mut engine = RuntimeEngine::new(
27//!     "rules/".into(),
28//!     vec![],
29//!     CorrelationConfig::default(),
30//!     false,
31//! );
32//! engine.load_rules().unwrap();
33//!
34//! let processor = LogProcessor::new(engine, Arc::new(NoopMetrics));
35//!
36//! let batch = vec![r#"{"EventID": 1}"#.to_string()];
37//! let results = processor.process_batch_lines(&batch, &|v| vec![v.clone()]);
38//! for result in &results {
39//!     for r in result.iter().filter(|r| r.is_detection()) {
40//!         println!("Detection: {}", r.header.rule_title);
41//!     }
42//! }
43//! ```
