Implementations

impl DCError

pub const UnknownSystemFailure: Self

A failure has occurred, such as the failure to generate a token.

pub const FeatureUnsupported: Self

DeviceCheck is unavailable on this device.

pub const InvalidInput: Self

An error code that indicates when your app provides data that isn’t formatted correctly.

pub const InvalidKey: Self

An error caused by a failed attempt to use the App Attest key.

You receive this error if something goes wrong with generating, retrieving, or using an App Attest cryptographic key, when:

• You call DeviceCheck/DCAppAttestService/attestKey:clientDataHash:completionHandler: for a key that’s already been attested.
• You call DeviceCheck/DCAppAttestService/generateAssertion:clientDataHash:completionHandler: with an unattested key.
• The App Attest service rejects the key.

pub const ServerUnavailable: Self

An error that indicates a failed attempt to contact the App Attest service during an attestation.

You receive this error when you call DeviceCheck/DCAppAttestService/attestKey:clientDataHash:completionHandler: and the framework isn’t able to complete the attestation. If you receive this error, try the attestation again later using the same key and the same value for the clientDataHash parameter. Retrying with the same inputs helps to preserve the risk metric for a given device.

Trait Implementations

impl Clone for DCError

fn clone(&self) -> DCError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DCError

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

Formats the value using the given formatter.

impl Encode for DCError

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for DCError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DCError

fn cmp(&self, other: &DCError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DCError

fn eq(&self, other: &DCError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DCError

fn partial_cmp(&self, other: &DCError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for DCError

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Copy for DCError

impl Eq for DCError
