Enum DataLinkError 

#[non_exhaustive]
pub enum DataLinkError {
    Io(Error),
    Encode(EncodeError),
    Decode(DecodeError),
    ConnectionClosed,
    Timeout,
    InvalidResponse(&'static str),
    MismatchedTransactionId {
        expected: u16,
        got: u16,
    },
    ResponseBufferTooSmall {
        needed: usize,
        available: usize,
    },
}

Errors that can occur during a transport-level operation.

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.

Io(Error)

Underlying I/O error (TCP socket, serial port, etc.).

Encode(EncodeError)

Failed to encode a request frame.

Decode(DecodeError)

Failed to decode a response frame.

ConnectionClosed

The remote peer closed the connection.

Timeout

The request timed out waiting for a response.

InvalidResponse(&'static str)

The response was structurally invalid.

MismatchedTransactionId

The response transaction ID did not match the request.

Fields

expected: u16

got: u16

ResponseBufferTooSmall

The caller-provided response buffer was too small for the response PDU.

Fields

needed: usize

available: usize

Trait Implementations

impl Debug for DataLinkError

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

Formats the value using the given formatter.

impl Display for DataLinkError

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

Formats the value using the given formatter.

impl Error for DataLinkError

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<DecodeError> for DataLinkError

fn from(source: DecodeError) -> Self

impl From<EncodeError> for DataLinkError

fn from(source: EncodeError) -> Self

Converts to this type from the input type.

impl From<Error> for DataLinkError

fn from(source: Error) -> Self

Converts to this type from the input type.
