Struct Unsigned

pub struct Unsigned { /* private fields */ }

A type modeling multiple bits.

The length number of bits represent an unsigned integer which is multiplied with the factor, and summed up with the offset. The endian controls the exact sequence of selected bits.

The following formula summarizes the relation between the bit sequence, factor, and offset:

result = bits_unsigned * factor + offset

Implementations

impl Unsigned

pub fn new( start: u16, length: u16, factor: f64, offset: f64, endian: Endian, ) -> Result<Unsigned, LengthError>

Constructs a new Unsigned signal.

Example

use cantools::signals::Unsigned;
use cantools::utils::Endian;
let sig = Unsigned::new(0, 8, 42.0, 1337.0, Endian::Little).unwrap();

Trait Implementations

impl Debug for Unsigned

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

Formats the value using the given formatter.

impl Decode<f64> for Unsigned

fn decode<D: CANRead>(&self, data: &D) -> T

Decodes the data.

impl Default for Unsigned

fn default() -> Self

Returns the “default value” for a type.

impl DefaultDecode<f64> for Unsigned

fn default_decode<D: CANRead>(&self, data: &D) -> T

Tries to decode a value. If the data is not decodable, a default value is returned. Otherwise, the decoded value is returned.

impl Encode<f64> for Unsigned

fn encode<D: CANWrite>(&self, data: &mut D, value: T)

Encodes value into the CAN-bus data data.

impl Max for Unsigned

type Item = f64

The type of return value of a call to max.

fn max(&self) -> Self::Item

The maximal value producible by the implementor.

impl Min for Unsigned

type Item = f64

The type of return value of a call to min.

fn min(&self) -> Self::Item

The minimal value producible by the implementor.

impl PartialEq for Unsigned

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

impl TryDecode<f64> for Unsigned

type Error = DecodeError

A type modeling the different possible failures of the decoding.

fn try_decode<D: CANRead>(&self, data: &D) -> Result<f64, Self::Error>

Tries to decode a value.

impl TryEncode<f64> for Unsigned

type Error = EncodeError

A type modelling the different possible failures of the encoding.

fn try_encode<D: CANWrite>( &self, data: &mut D, value: f64, ) -> Result<(), Self::Error>

Tries to encode value into data.
