Enum Error 

pub enum Error {
    DBusError(Error),
    NoConnection,
    IOError(Error),
    JSONError(Error),
    NotificationNotFound(u32),
    ConnectionInitializedTwice,
}

Enum representing possible errors to happen during the usage of crate::NotificationService.

Variants

DBusError(Error)

D-Bus error. Carries [zbus::Error] inside.

Usually returned if another notification daemon is running on the session bus.

NoConnection

Returned if attempted to call methods that involve D-Bus interaction and have not called crate::NotificationService::run yet.

IOError(Error)

Returned in case of I/O file errors. Carries std::io::Error.

JSONError(Error)

Returned if JSON parsing of the notification history failed. Carries serde_json::Error.

Usually indicates that the JSON markup is corrupted.

NotificationNotFound(u32)

Returned if the notification with the given ID is not found.

ConnectionInitializedTwice

Returned if crate::NotificationService::run is called more than once.

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.
