The error type for zbus.

The various errors that can be reported by this crate.

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.

InterfaceNotFound

Interface not found

Address

Invalid D-Bus address.

Tuple Fields of Address

0: String

Io

An I/O error.

Tuple Fields of Io

0: Error

InsufficientData

Insufficient data provided to create a valid D-Bus message.

InvalidField

Invalid message field.

ExcessData

Data too large.

Variant

A zvariant error.

Tuple Fields of Variant

0: VariantError

Names

A zbus_names error.

Tuple Fields of Names

0: NamesError

IncorrectEndian

Endian signature invalid or doesn’t match expectation.

Handshake

Initial handshake error.

Tuple Fields of Handshake

0: String

InvalidReply

Unexpected or incorrect reply.

MethodError

A D-Bus method error reply.

Tuple Fields of MethodError

0: OwnedErrorName1: Option<String>2: Arc<Message>

MissingField

A required field is missing in the message headers.

InvalidGUID

Invalid D-Bus GUID.

Unsupported

Unsupported function, or support currently lacking.

FDO

A fdo::Error transformed into Error.

Tuple Fields of FDO

0: Box<Error>

SerdeXml

An XML error

Tuple Fields of SerdeXml

0: Error

NoBodySignature

UnmatchedBodySignature

Unmatching/bad body signature in the message.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
