Enum Id

pub enum Id {
    Standard(StandardId),
    Extended(ExtendedId),
}

A CAN Identifier (standard or extended).

Variants

Standard(StandardId)

Standard 11-bit Identifier (0..=0x7FF).

Extended(ExtendedId)

Extended 29-bit Identifier (0..=0x1FFF_FFFF).

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl From<ExtendedId> for Id

fn from(id: ExtendedId) -> Id

Converts to this type from the input type.

impl From<StandardId> for Id

fn from(id: StandardId) -> Id

Converts to this type from the input type.

impl Hash for Id

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

where __H: Hasher,

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 Ord for Id

Implement Ord according to the CAN arbitration rules

When performing arbitration, frames are looked at bit for bit starting from the beginning. A bit with the value 0 is dominant and a bit with value of 1 is recessive.

When two devices are sending frames at the same time, as soon as the first bit is found which differs, the frame with the corresponding dominant 0 bit will win and get to send the rest of the frame.

This implementation of Ord for Id will take this into consideration and when comparing two different instances of Id the “smallest” will always be the ID which would form the most dominant frame, all other things being equal.

fn cmp(&self, other: &Id) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Id

fn eq(&self, other: &Id) -> 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 PartialOrd for Id

fn partial_cmp(&self, other: &Id) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
