36/// Represents a complete DBC (CAN database) file.
37///
38/// A `Dbc` contains:
39/// - An optional version string
40/// - A list of nodes (ECUs)
41/// - A collection of messages with their signals
42///
43/// # Examples
44///
45/// ```rust,no_run
46/// use dbc_rs::Dbc;
47///
48/// let dbc_content = r#"VERSION "1.0"
49///
50/// BU_: ECM TCM
51///
52/// BO_ 256 EngineData : 8 ECM
53///  SG_ RPM : 0|16@0+ (0.25,0) [0|8000] "rpm" TCM
54/// "#;
55///
56/// let dbc = Dbc::parse(dbc_content)?;
57/// println!("Parsed {} messages", dbc.messages().len());
58/// # Ok::<(), dbc_rs::Error>(())
