//!
//! # Quick Start
//!
//! ## Basic J1939 Processing
//!
//! ```no_run
//! use oxirs_canbus::{J1939Processor, CanFrame, CanId, PgnRegistry};
//!
//! // Create J1939 processor with transport protocol support
//! let mut processor = J1939Processor::new();
//! let registry = PgnRegistry::with_standard_decoders();
//!
//! // Process incoming CAN frames
//! let can_id = CanId::extended(0x0CF00400).unwrap(); // EEC1
//! let frame = CanFrame::new(can_id, vec![0, 125, 125, 0x80, 0x3E, 0, 0, 125]).unwrap();
//!
//! if let Some(message) = processor.process(&frame) {
//!     // Decode the message using PGN registry
//!     if let Some(decoded) = registry.decode(&message) {
//!         for signal in &decoded.signals {
//!             println!("{}: {} {}", signal.name, signal.value, signal.unit);
//!         }
//!     }
//! }
//! ```
//!
//! ## Linux SocketCAN Client
//!
//! ```no_run,ignore
//! use oxirs_canbus::{CanbusClient, CanbusConfig};
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     let config = CanbusConfig {
//!         interface: "can0".to_string(),
//!         j1939_enabled: true,
//!         ..Default::default()
//!     };
//!
//!     let mut client = CanbusClient::new(config)?;
//!     client.start().await?;
//!
//!     while let Some(frame) = client.recv_frame().await {
//!         println!("Received: {:?}", frame);
//!     }
//!
//!     Ok(())
//! }
//! ```
//!
//! ## DBC File Format (Month 4)
//!
//! ```dbc
//! BO_ 1234 EngineData: 8 Engine
//!   SG_ EngineSpeed : 0|16@1+ (0.125,0) [0|8191.875] "rpm" ECU
//!   SG_ EngineTemp : 16|8@1+ (1,-40) [-40|215] "deg C" ECU
//! ```
//!
//! # J1939 Protocol Support
//!
//! This crate provides comprehensive J1939 support:
//!
//! - **PGN extraction** from 29-bit CAN IDs
//! - **Multi-packet messages** via Transport Protocol (TP.CM/TP.DT)
//! - **Address claiming** for network participation
//! - **Common PGN decoders**:
//!   - EEC1 (61444): Engine speed, torque
//!   - EEC2 (61443): Accelerator position
//!   - CCVS (65265): Vehicle speed
//!   - ET1 (65262): Engine temperatures
//!   - EFL/P1 (65263): Fluid levels/pressures
//!   - LFE (65266): Fuel economy
//!   - AMB (65269): Ambient conditions
//!   - VEP1 (65271): Electrical power
//!
//! # Configuration
//!
//! TOML configuration example:
//!
//! ```toml
//! [[stream.external_systems]]
//! type = "CANbus"
//! interface = "can0"
//! j1939_enabled = true
//! dbc_file = "vehicle.dbc"
//!
//! [stream.external_systems.rdf_mapping]
//! device_id = "vehicle001"
//! base_iri = "http://automotive.example.com/vehicle"
//! graph_iri = "urn:automotive:can-data"
//! ```
//!
//! # CLI Commands
//!
//! The `oxirs` CLI provides CANbus monitoring and DBC tools:
//!
//! ```bash
//! # Monitor CAN interface
//! oxirs canbus monitor --interface can0 --dbc vehicle.dbc --j1939
//!
//! # Parse DBC file
//! oxirs canbus parse-dbc --file vehicle.dbc --detailed
//!
//! # Decode CAN frame
//! oxirs canbus decode --id 0x0CF00400 --data DEADBEEF --dbc vehicle.dbc
//!
//! # Generate SAMM Aspect Models
//! oxirs canbus to-samm --dbc vehicle.dbc --output ./models/
//!
//! # Generate RDF from live CAN data
//! oxirs canbus to-rdf --interface can0 --dbc vehicle.dbc --output data.ttl --count 1000
//! ```
//!
