Enum NotifyError 

pub enum NotifyError {
    Spawn(Box<Error>),
    NonZeroExit {
        code: i32,
        stderr: Box<str>,
    },
    NoBackend,
}

Errors that can occur while dispatching a notification.

Kept ≤ 128 bytes: io::Error is boxed, stderr string is boxed.

Variants

Spawn(Box<Error>)

Failed to spawn the notification subprocess.

NonZeroExit

Notification subprocess exited non-zero.

Fields

code: i32

Exit code.

stderr: Box<str>

Captured stderr output (boxed to keep enum small).

NoBackend

No suitable backend was found (should not occur; Stderr is always available).

Trait Implementations

impl Debug for NotifyError

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

Formats the value using the given formatter.

impl Display for NotifyError

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

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 From<NotifyError> for Error

fn from(e: NotifyError) -> Self

Converts to this type from the input type.
