Enum MessagingError 

pub enum MessagingError {
    Core(CoreError),
    Http(Error),
    Api {
        status: u16,
        message: String,
        error_code: Option<String>,
    },
    BatchTooLarge {
        actual: usize,
        max: usize,
    },
}

The top-level error type for all messaging module operations.

Variants

Core(CoreError)

A lower-level, service-independent error occurred.

Http(Error)

The underlying HTTP request failed.

Api

The FCM v1 API returned an error response.

Fields

status: u16

HTTP status code returned by the API.

message: String

Human-readable error message returned by the API.

error_code: Option<String>

Machine-readable error code, when the API provides one (e.g. UNREGISTERED, INVALID_ARGUMENT, QUOTA_EXCEEDED).

BatchTooLarge

More than crate::messaging::MAX_BATCH_SIZE messages/tokens were passed to a batch operation (crate::messaging::MessagingClient::send_each or crate::messaging::MessagingClient::send_each_for_multicast).

Fields

actual: usize

The number of messages/tokens that were passed in.

max: usize

The maximum allowed per call.

Trait Implementations

impl Debug for MessagingError

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

Formats the value using the given formatter.

impl Display for MessagingError

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

Formats the value using the given formatter.

impl Error for MessagingError

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.
