Enum rodbus::FrameParseError

pub enum FrameParseError {
    MbapLengthZero,
    FrameLengthTooBig(usize, usize),
    UnknownProtocolId(u16),
    UnknownFunctionCode(u8),
    CrcValidationFailure(u16, u16),
}

Errors that occur while parsing a frame off a stream (TCP or serial)

Variants

MbapLengthZero

Received TCP frame with the length field set to zero

FrameLengthTooBig(usize, usize)

Received TCP or RTU frame with length that exceeds max allowed size

UnknownProtocolId(u16)

Received TCP frame within non-Modbus protocol id

UnknownFunctionCode(u8)

Unknown function code (only emitted in RTU parsing)

CrcValidationFailure(u16, u16)

RTU CRC validation failed

Trait Implementations

impl Clone for FrameParseError

fn clone(&self) -> FrameParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameParseError

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

Formats the value using the given formatter.

impl Display for FrameParseError

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

Formats the value using the given formatter.

impl Error for FrameParseError

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

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<FrameParseError> for RequestError

fn from(err: FrameParseError) -> Self

Converts to this type from the input type.

impl Ord for FrameParseError

fn cmp(&self, other: &FrameParseError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<FrameParseError> for FrameParseError

fn eq(&self, other: &FrameParseError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<FrameParseError> for FrameParseError

fn partial_cmp(&self, other: &FrameParseError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
