Binding to LAError of LocalAuthentication

Error codes that the framework returns when policy evaluation fails.

Variants

LAErrorAppCancel = -9

The app canceled authentication.

LAErrorSystemCancel = -4

The system canceled authentication.

LAErrorUserCancel = -2

The user tapped the cancel button in the authentication dialog.

LAErrorBiometryDisconnected = -13

The device supports biometry only using a removable accessory, but the paired accessory isn’t connected.

LAErrorBiometryLockout = -8

Biometry is locked because there were too many failed attempts.

LAErrorBiometryNotAvailable = -6

Biometry is not available on the device.

LAErrorBiometryNotEnrolled = -7

The user has no enrolled biometric identities.

LAErrorBiometryNotPaired = -12

The device supports biometry only using a removable accessory, but no accessory is paired.

LAErrorAuthenticationFailed = -1

The user failed to provide valid credentials.

LAErrorInvalidContext = -10

The context was previously invalidated.

LAErrorInvalidDimensions = -14

undocumented

LAErrorNotInteractive = -1_004

Displaying the required authentication user interface is forbidden.

LAErrorPasscodeNotSet = -5

A passcode isn’t set on the device.

LAErrorUserFallback = -3

The user tapped the fallback button in the authentication dialog, but no fallback is available for the authentication policy.

LAErrorWatchNotAvailable = -11

An attempt to authenticate with Apple Watch failed.

Trait Implementations

impl Clone for LAError

fn clone(&self) -> LAError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LAError

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

Formats the value using the given formatter.

impl Display for LAError

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

Formats the value using the given formatter.

impl Error for LAError

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.
