Error type for CTAP operations

Variants

Success

The given operation was successful

DoesAlreadyExist

The given value already exists

DoesNotExist

The requested value doesn’t exist

KeyStoreFull

Credentials can’t be inserted into the key-store

OutOfMemory

The client ran out of memory

Timeout

The operation timed out

Other

Unspecified operation

InitializationFailed

Initialization failed

InvalidCallbackResult

Invalid callback result

CborCommandFailed(i32)

CBOR command failed

InvalidClientDataHash

Invalid client data hash (must be 32 bytes)

CtapError(u8)

CTAP error with status code

IoError(String)

IO error (from transport operations)

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &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

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 From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StatusCode

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<StatusCode> for Error

fn from(status: StatusCode) -> Self

Converts to this type from the input type.

impl From<i32> for Error

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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.
