Struct SignalList 

pub struct SignalList { /* private fields */ }

Encapsulates the signals array for a message

Uses Vec<Signal> for dynamic sizing.

Implementations

impl SignalList

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

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>

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) {
    assert_eq!(signal.name(), "RPM");
}

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

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") {
    assert_eq!(signal.name(), "RPM");
    assert_eq!(signal.factor(), 0.25);
}

Trait Implementations

impl Clone for SignalList

fn clone(&self) -> SignalList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalList

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

Formats the value using the given formatter.

impl From<&[Signal]> for SignalList

fn from(signals: &[Signal]) -> Self

Converts to this type from the input type.

impl From<Vec<Signal>> for SignalList

Available on crate feature std only.

fn from(signals: Vec<Signal>) -> Self

Converts to this type from the input type.

impl Hash for SignalList

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 PartialEq for SignalList

fn eq(&self, other: &SignalList) -> 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.
