Enum PushRejection 

pub enum PushRejection {
    DeviceNotRegistered,
    MessageTooBig,
    MessageRateExceeded,
    InvalidCredentials,
    ProviderError,
    Other(String),
}

Why a provider rejected one notification.

The variants cover the vocabulary push providers actually return. Anything outside it becomes PushRejection::Other with the provider’s own string, so a new provider code is visible in logs instead of being silently dropped.

Variants

DeviceNotRegistered

The token no longer belongs to an installed app.

This is permanent. Delete the token; see PushOutcome::is_token_dead.

MessageTooBig

The serialized notification exceeded the provider’s size limit.

MessageRateExceeded

Too many notifications were sent to this token in too short a window.

InvalidCredentials

The provider credential was missing, malformed, or rejected.

ProviderError

The upstream platform (APNs, FCM) refused the notification.

Other(String)

A provider code outside the known vocabulary.

Implementations

impl PushRejection

pub fn from_code(code: &str) -> Self

Parses a provider error code into a rejection.

pub const fn is_retryable(&self) -> bool

Returns whether resending the same notification can succeed.

Only PushRejection::MessageRateExceeded and PushRejection::ProviderError are worth another attempt. A dead token, an oversized payload, and a rejected credential all fail the same way again.
