Enum ResponsePacketError 

pub enum ResponsePacketError {
    TooShort(usize),
    CRCMismatch {
        expected: u16,
        received: u16,
    },
    UnexpectedResponder(u8),
    InvalidFormat,
}

Errors that can occur while validating and decoding a Modbus RTU response packet.

Variants

TooShort(usize)

The response frame is shorter than the minimum Modbus RTU length.

CRCMismatch

Calculated CRC does not match the CRC bytes present in the frame.

Fields

expected: u16

received: u16

UnexpectedResponder(u8)

The response came from a different Modbus slave than the request targeted.

InvalidFormat

The payload failed structural validation (unexpected function code, byte count mismatch, etc.).

Trait Implementations

impl Clone for ResponsePacketError

fn clone(&self) -> ResponsePacketError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResponsePacketError

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

Formats the value using the given formatter.

impl Display for ResponsePacketError

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

Formats the value using the given formatter.

impl Error for ResponsePacketError

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 ResponsePacketError

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