Enum ExceptionCode

pub enum ExceptionCode {
    IllegalFunction,
    IllegalDataAddress,
    IllegalDataValue,
    ServerDeviceFailure,
    Acknowledge,
    ServerDeviceBusy,
    MemoryParityError,
    GatewayPathUnavailable,
    GatewayTargetDevice,
    Custom(u8),
}

A server (slave) exception.

Variants

IllegalFunction

0x01

IllegalDataAddress

0x02

IllegalDataValue

0x03

ServerDeviceFailure

0x04

Acknowledge

0x05

ServerDeviceBusy

0x06

MemoryParityError

0x08

GatewayPathUnavailable

0x0A

GatewayTargetDevice

0x0B

Custom(u8)

None of the above.

Although encoding one of the predefined values as this is possible, it is not recommended. Instead, prefer to use Self::new() to prevent such ambiguities.

Implementations

impl ExceptionCode

pub const fn new(value: u8) -> Self

Create a new ExceptionCode with value.

Trait Implementations

impl Clone for ExceptionCode

fn clone(&self) -> ExceptionCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExceptionCode

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

Formats the value using the given formatter.

impl Display for ExceptionCode

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

Formats the value using the given formatter.

impl Error for ExceptionCode

fn description(&self) -> &str

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

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

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

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 From<ExceptionCode> for u8

fn from(from: ExceptionCode) -> Self

Converts to this type from the input type.

impl PartialEq for ExceptionCode

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