Implementations

impl ErrorCode

pub fn request(address: Address) -> Vec<u8>

Creates a request frame to read the BMS error codes.

Arguments

• address - The address of the BMS (should be Address::Host when sending from host).

Returns

A byte vector representing the request frame.

This is a low-level function. Users might prefer client methods.

pub fn reply_size() -> usize

Expected size of the reply frame for an error codes request.

pub fn decode(rx_buffer: &[u8]) -> Result<Vec<Self>, Error>

Decodes the error codes from a response frame. The BMS returns a bitmask where each bit corresponds to an error. This function returns a Vec<ErrorCode> containing all active errors.

Arguments

• rx_buffer - The response frame received from the BMS.

Returns

A Result containing a Vec<ErrorCode> of active errors or an Error if decoding fails.

This is a low-level function. Users might prefer client methods.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Error for ErrorCode

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> 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 Serialize for ErrorCode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
