Error type for Bark APNs operations.

The enum is non-exhaustive so the crate can add more precise variants later without breaking downstream code. Applications can convert it into anyhow::Error with ?, while libraries can match individual variants.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidKeyLength

The encryption key length does not match the selected AES algorithm.

Fields

algorithm: &'static str

Bark algorithm name, such as AES128.

expected: usize

Expected UTF-8 byte length.

actual: usize

Actual UTF-8 byte length.

InvalidIvLength

The IV length does not match the selected AES mode.

Fields

mode: &'static str

Bark mode name, such as CBC.

expected: usize

Expected UTF-8 byte length.

actual: usize

Actual UTF-8 byte length.

InvalidCollapseId

The message id is too long to be used as an APNs collapse id.

Fields

actual: usize

Actual UTF-8 byte length.

MissingMessageIdForDelete

A delete message was serialized or sent without an id.

EmptyMessage

A normal non-delete message has neither body nor markdown.

InvalidHeaderValue

A value could not be encoded as an APNs HTTP header.

Fields

name: &'static str

Header name being constructed.

source: InvalidHeaderValue

Underlying header parsing error.

HttpClient(Error)

The HTTP client could not be constructed.

Http(Error)

An HTTP request failed before receiving a per-device APNs response.

Jwt(Error)

APNs provider-token generation failed.

Json(Error)

JSON serialization failed.

Encryption

Encryption failed after input validation.

Random(String)

Random IV generation failed.

Tuple Fields

0: String

Randomness provider error text.

ApnsFailures(String)

One or more device tokens failed during a multi-device send.

Tuple Fields

0: String

Human-readable summary containing failed device tokens and reasons.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
