Enum Exception 

pub enum Exception {
    IllegalFunction,
    IllegalDataAddress,
    IllegalDataValue,
    SlaveDeviceFailure,
    Acknowledge,
}

Exception types

Variants

IllegalFunction

Code 1

Function code received in the query is not recognized or allowed by server

IllegalDataAddress

Code 2

Data address of some or all the required entities are not allowed or do not exist in server

IllegalDataValue

Code 3

Value is not accepted by server

SlaveDeviceFailure

Code 5

Unrecoverable error occurred while server was attempting to perform requested action

Acknowledge

Code 6

Server has accepted request and is processing it, but a long duration of time is required. This response is returned to prevent a timeout error from occurring in the client. client can next issue a Poll Program Complete message to determine whether processing is completed

Trait Implementations

impl Clone for Exception

fn clone(&self) -> Exception

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exception

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

Formats the value using the given formatter.

impl Hash for Exception

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 Ord for Exception

fn cmp(&self, other: &Exception) -> 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 Exception

fn eq(&self, other: &Exception) -> 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 Exception

fn partial_cmp(&self, other: &Exception) -> 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.

impl TryFrom<u8> for Exception

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self>

Performs the conversion.

impl Eq for Exception

impl StructuralPartialEq for Exception
