Enum PushError 

pub enum PushError {
    Unregistered,
    Rejected(String),
    Transient(String),
}

Push failures. Unregistered is separated because the caller must act on it — the device token is dead and should be pruned — where the others are transient or a bad request.

Variants

Unregistered

The provider says the token is no longer valid (APNs 410): delete it.

Rejected(String)

The provider rejected the request (a 4xx that is not 410); not retryable without a change.

Transient(String)

A transient failure (a 5xx, a transport error): retry later.

Trait Implementations

impl Clone for PushError

fn clone(&self) -> PushError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PushError

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

Formats the value using the given formatter.

impl Display for PushError

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

Formats the value using the given formatter.

impl Error for PushError

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.
