Implementations

impl LAError

pub const AuthenticationFailed: Self

Authentication was not successful because user failed to provide valid credentials.

pub const UserCancel: Self

Authentication was canceled by user (e.g. tapped Cancel button).

pub const UserFallback: Self

Authentication was canceled because the user tapped the fallback button (Enter Password).

pub const SystemCancel: Self

Authentication was canceled by system (e.g. another application went to foreground).

pub const PasscodeNotSet: Self

Authentication could not start because passcode is not set on the device.

pub const TouchIDNotAvailable: Self

👎Deprecated: use LAErrorBiometryNotAvailable

Authentication could not start because Touch ID is not available on the device.

pub const TouchIDNotEnrolled: Self

👎Deprecated: use LAErrorBiometryNotEnrolled

Authentication could not start because Touch ID has no enrolled fingers.

pub const TouchIDLockout: Self

👎Deprecated: use LAErrorBiometryLockout

Authentication was not successful because there were too many failed Touch ID attempts and Touch ID is now locked. Passcode is required to unlock Touch ID, e.g. evaluating LAPolicyDeviceOwnerAuthenticationWithBiometrics will ask for passcode as a prerequisite.

pub const AppCancel: Self

Authentication was canceled by application (e.g. invalidate was called while authentication was in progress).

pub const InvalidContext: Self

LAContext passed to this call has been previously invalidated.

pub const BiometryNotAvailable: Self

Authentication could not start because biometry is not available on the device.

pub const BiometryNotEnrolled: Self

Authentication could not start because biometry has no enrolled identities.

pub const BiometryLockout: Self

Authentication was not successful because there were too many failed biometry attempts and biometry is now locked. Passcode is required to unlock biometry, e.g. evaluating LAPolicyDeviceOwnerAuthenticationWithBiometrics will ask for passcode as a prerequisite.

pub const NotInteractive: Self

Authentication failed because it would require showing UI which has been forbidden by using interactionNotAllowed property.

pub const WatchNotAvailable: Self

👎Deprecated

Authentication could not start because there was no paired watch device nearby.

pub const CompanionNotAvailable: Self

Authentication could not start because there was no paired companion device nearby.

pub const BiometryNotPaired: Self

Authentication could not start because this device supports biometry only via removable accessories and no accessory has been paired.

pub const BiometryDisconnected: Self

Authentication could not start because this device supports biometry only via removable accessories and the paired accessory is not connected.

pub const InvalidDimensions: Self

Authentication could not start because dimensions of embedded UI are invalid.

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 Encode for LAError

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for LAError

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 LAError

fn cmp(&self, other: &LAError) -> 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 LAError

fn eq(&self, other: &LAError) -> 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 LAError

fn partial_cmp(&self, other: &LAError) -> 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 LAError

const ENCODING_REF: Encoding

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

impl Copy for LAError

impl Eq for LAError

impl StructuralPartialEq for LAError
