Struct NotifyError 

pub struct NotifyError { /* private fields */ }

Why a notify backend failed to deliver, and whether asking again could help.

The retryable half is what NotifyJob turns into JobOutcome::Retry or JobOutcome::Failed, so the distinction has to be drawn where the failure happens rather than guessed from a string afterwards. The default — NotifyError::new — is retryable, because most of these are transport; a backend that knows better says so with NotifyError::permanent.

Implementations

impl NotifyError

pub fn new(detail: impl Into<String>) -> Self

A failure that may not recur: a refused connection, a timeout, a 503.

pub fn permanent(detail: impl Into<String>) -> Self

A failure that will repeat identically however many times it is tried: a template that does not render, a URL that does not parse, a webhook that answers 400.

pub fn retryable(&self) -> bool

Whether another attempt could plausibly succeed.

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>)
