Enum ClientError 

#[non_exhaustive]
pub enum ClientError {
    DataLink(DataLinkError),
    Encode(EncodeError),
    Decode(DecodeError),
    Timeout,
    Exception(ExceptionResponse),
    InvalidResponse(InvalidResponseKind),
}

Errors that can occur when executing a Modbus request through ModbusClient.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DataLink(DataLinkError)

Transport-level error (I/O, connection closed, etc.).

Encode(EncodeError)

Failed to encode the request PDU.

Decode(DecodeError)

Failed to decode the response PDU.

Timeout

The device did not respond within the configured timeout.

Exception(ExceptionResponse)

The device returned a Modbus exception response.

InvalidResponse(InvalidResponseKind)

The response was structurally invalid.

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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.
