Struct Error 

pub struct Error { /* private fields */ }

An error raised while talking to the bus.

Implementations

impl Error

pub fn remote(name: impl AsRef<str>, message: impl Display) -> Self

Construct an error which is reported back to a caller as an error reply.

Examples

use tokio_dbus_runtime::Error;

let error = Error::remote("com.example.Error.Busy", "Try again later");
assert_eq!(error.name(), Some("com.example.Error.Busy"));

pub fn name(&self) -> Option<&str>

The D-Bus error name, if this error came from, or is destined for, an error reply.

A timeout raised by this end reports itself as org.freedesktop.DBus.Error.NoReply, which is the name every implementation uses for a call which was not answered.

pub fn is_remote(&self) -> bool

Test if this error is an error reply from the remote end.

When this is false the error was raised locally, such as a transport failure or a timeout, and retrying against the same peer is unlikely to behave differently.

Examples

use tokio_dbus_runtime::Error;

let error = Error::remote("com.example.Error.Busy", "Try again later");
assert!(error.is_remote());

pub fn is_name_taken(&self) -> bool

Test if this error was raised by Connection::acquire_name because the name was already taken.

pub fn is_timeout(&self) -> bool

Test if this error is a call which timed out.

See Connection::set_default_timeout.

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)>

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
