Enum Error 

pub enum Error {
    UnexpectedDataLength {
        expected: usize,
        got: usize,
    },
    InvalidData {
        details: String,
    },
    InvalidValueCode {
        entity: String,
        code: u16,
    },
    EncodeError {
        reason: String,
    },
}

A comprehensive error type for all operations within the protocol module.

This enum consolidates errors that can occur during the decoding data, encoding of values, or validation of parameters.

Variants

UnexpectedDataLength

Error indicating that the data received from a Modbus read has an unexpected length.

Fields

expected: usize

got: usize

InvalidData

Error for malformed data within a register, e.g., an unexpected non-zero upper byte.

Fields

details: String

InvalidValueCode

Error for an invalid value read from a register, e.g., an undefined baud rate code.

Fields

entity: String

code: u16

EncodeError

Error for an attempt to encode a value that is not supported, e.g., a NaN temperature.

Fields

reason: String

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

Available on crate features tokio-rtu-sync or tokio-tcp-sync or tokio-rtu or tokio-tcp only.

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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