Struct Signals 

pub struct Signals<'a> { /* private fields */ }

Encapsulates the signals array and count for a message

Storage strategy:

• no_std: Uses fixed-size array [Option<Signal>; MAX_SIGNALS_PER_MESSAGE]
• alloc: Uses heap-allocated Box<[Option<Signal>]> for dynamic sizing

Implementations

impl<'a> Signals<'a>

pub fn iter(&self) -> impl Iterator<Item = &Signal<'a>> + '_

Get an iterator over the signals

Examples

use dbc_rs::Dbc;

let dbc = Dbc::parse("VERSION \"1.0\"\n\nBU_: ECM\n\nBO_ 256 Engine : 8 ECM\n SG_ RPM : 0|16@1+ (0.25,0) [0|8000] \"rpm\"")?;
let message = dbc.messages().at(0).unwrap();
for signal in message.signals().iter() {
    println!("Signal: {} (start: {}, length: {})", signal.name(), signal.start_bit(), signal.length());
}

pub fn len(&self) -> usize

Get the number of signals

Examples

use dbc_rs::Dbc;

let dbc = Dbc::parse("VERSION \"1.0\"\n\nBU_: ECM\n\nBO_ 256 Engine : 8 ECM\n SG_ RPM : 0|16@1+ (0.25,0) [0|8000] \"rpm\"")?;
let message = dbc.messages().at(0).unwrap();
assert_eq!(message.signals().len(), 1);

pub fn is_empty(&self) -> bool

Returns true if there are no signals

Examples

use dbc_rs::Dbc;

let dbc = Dbc::parse("VERSION \"1.0\"\n\nBU_: ECM\n\nBO_ 256 Engine : 8 ECM")?;
let message = dbc.messages().at(0).unwrap();
assert!(message.signals().is_empty());

pub fn at(&self, index: usize) -> Option<&Signal<'a>>

Get a signal by index, or None if index is out of bounds

Examples

use dbc_rs::Dbc;

let dbc = Dbc::parse("VERSION \"1.0\"\n\nBU_: ECM\n\nBO_ 256 Engine : 8 ECM\n SG_ RPM : 0|16@1+ (0.25,0) [0|8000] \"rpm\"")?;
let message = dbc.messages().at(0).unwrap();
if let Some(signal) = message.signals().at(0) {
    println!("First signal: {}", signal.name());
}

pub fn find(&self, name: &str) -> Option<&Signal<'a>>

Find a signal by name, or None if not found

Examples

use dbc_rs::Dbc;

let dbc = Dbc::parse("VERSION \"1.0\"\n\nBU_: ECM\n\nBO_ 256 Engine : 8 ECM\n SG_ RPM : 0|16@1+ (0.25,0) [0|8000] \"rpm\"")?;
let message = dbc.messages().at(0).unwrap();
if let Some(signal) = message.signals().find("RPM") {
    println!("Found RPM signal with factor: {}", signal.factor());
}

Trait Implementations

impl<'a> Clone for Signals<'a>

fn clone(&self) -> Signals<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Signals<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Hash for Signals<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for Signals<'a>

fn eq(&self, other: &Signals<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
