33/// Represents a complete DBC (CAN database) file.
34///
35/// A `Dbc` contains:
36/// - An optional version string
37/// - A list of nodes (ECUs)
38/// - A collection of messages with their signals
39///
40/// # Examples
41///
42/// ```rust,no_run
43/// use dbc_rs::Dbc;
44///
45/// let dbc_content = r#"VERSION "1.0"
46///
47/// BU_: ECM TCM
48///
49/// BO_ 256 EngineData : 8 ECM
50///  SG_ RPM : 0|16@0+ (0.25,0) [0|8000] "rpm" TCM
51/// "#;
52///
53/// let dbc = Dbc::parse(dbc_content)?;
54/// println!("Parsed {} messages", dbc.messages().len());
