Enum NotifyError 

pub enum NotifyError {
    Unavailable,
    Unsupported(Unsupported<Feature>),
    Invalid(&'static str),
    Failed(String),
}

Why a notification could not be shown, scheduled or withdrawn.

Variants

Unavailable

This host has no notification service, or this process may not use it (an unbundled macOS binary).

Unsupported(Unsupported<Feature>)

This target cannot do what was asked; see availability.

Invalid(&'static str)

The request itself is malformed (an empty tag).

Failed(String)

The service rejected the request.

Trait Implementations

impl Clone for NotifyError

fn clone(&self) -> NotifyError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NotifyError

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

Formats the value using the given formatter.

impl Display for NotifyError

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

Formats the value using the given formatter.

impl Error for NotifyError

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 PartialEq for NotifyError

fn eq(&self, other: &NotifyError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
