Why a call did not do what it was asked.

Variants

InvalidKey

The key is empty, longer than MAX_KEY_LEN bytes, or contains a control character.

InvalidReason

The reason text for a user-presence read is empty.

TooLarge

The secret is longer than MAX_SECRET_LEN bytes.

NotFound

No item has this key.

NeedsPresence

The item needs the person present and this was the synchronous get; use get_async or get_future.

Cancelled

The person dismissed the verification dialog.

AuthFailed

The person did not pass the verification dialog.

Lockout

Biometrics are locked after too many attempts; the device credential clears it.

PasscodeNotSet

The item needs a device passcode, PIN or password and none is set.

Unreadable

The item exists but cannot be read: its key was invalidated (the device credential was removed, a protected key’s biometric enrollment changed), its file is damaged, or it was written by another user account. The item is left in place; remove clears it.

Locked

The store is locked and cannot be unlocked now: a Linux keyring whose unlock dialog was dismissed, an Apple item read while the device is locked.

Unavailable

The store is not reachable: no Secret Service on this Linux session, no logon session on Windows, no app context on Android.

Unsupported

This platform has no store, or this Protection level has no realization here.

Platform(String)

A platform error outside the vocabulary above, with the platform’s message.

Trait Implementations

impl Clone for KeychainError

fn clone(&self) -> KeychainError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeychainError

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

Formats the value using the given formatter.

impl Display for KeychainError

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

Formats the value using the given formatter.

impl Eq for KeychainError

impl Error for KeychainError

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.

impl PartialEq for KeychainError

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

Equality operator ==.

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

Inequality operator !=.
