26/// Represents a CAN signal within a message.
27///
28/// A `Signal` contains:
29/// - A name
30/// - Start bit position and length
31/// - Byte order (big-endian or little-endian)
32/// - Signed/unsigned flag
33/// - Factor and offset for physical value conversion
34/// - Min/max range
35/// - Optional unit string
36/// - Receivers (nodes that receive this signal)
37///
38/// # Examples
39///
40/// ```rust,no_run
41/// use dbc_rs::Dbc;
42///
43/// let dbc = Dbc::parse(r#"VERSION "1.0"
44///
45/// BU_: ECM

47/// BO_ 256 Engine : 8 ECM
48///  SG_ RPM : 0|16@1+ (0.25,0) [0|8000] "rpm" *
49/// "#)?;
50///
51/// let message = dbc.messages().at(0).unwrap();
52/// let signal = message.signals().at(0).unwrap();
53/// println!("Signal: {} (bits: {}-{})", signal.name(), signal.start_bit(), signal.start_bit() + signal.length() - 1);
