Top-level error type for the BACnet library.

Variants

Protocol

BACnet protocol error response (Clause 20.1.7).

Fields

class: u32

Error class value.

code: u32

Error code value.

Reject

BACnet reject PDU (Clause 20.1.5).

Fields

reason: u8

Reject reason value.

Abort

BACnet abort PDU (Clause 20.1.6).

Fields

reason: u8

Abort reason value.

Encoding(String)

Error encoding a PDU.

Decoding

Error decoding received data.

Fields

offset: usize

Byte offset where the error occurred.

message: String

Description of what went wrong.

Transport(Error)

Transport-level I/O error.

Timeout(Duration)

Request timed out.

Segmentation(String)

Segmentation assembly error.

BufferTooShort

Buffer too short for the expected data.

Fields

need: usize

Minimum bytes needed.

have: usize

Bytes actually available.

InvalidTag(String)

Invalid tag encountered during decode.

OutOfRange(String)

Value out of valid range.

Implementations

impl Error

pub fn decoding(offset: usize, message: impl Into<String>) -> Self

Create a decoding error at the given byte offset.

pub fn buffer_too_short(need: usize, have: usize) -> Self

Create a buffer-too-short error.

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

fn from(source: Error) -> Self

Converts to this type from the input type.
