U2F or CTAP1 error variants

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Success = 0

Indicates successful response.

InvalidCommand = 1

The command is not a valid CTAP command.

InvalidParameter = 2

The command included an invalid parameter.

InvalidLength = 3

Invalid message or item length.

InvalidSequence = 4

Invalid message sequencing.

Timeout = 5

Message timed out.

ChannelBusy = 6

Channel busy. Client SHOULD retry the request after a short delay. Note that the client MAY abort the transaction if the command is no longer relevant.

LockRequired = 10

Command requires channel lock.

InvalidChannel = 11

Command not allowed on this cid.

Other = 127

Other unspecified error.

Trait Implementations

impl Clone for U2FError

fn clone(&self) -> U2FError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for U2FError

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

Formats the value using the given formatter.

impl From<U2FError> for StatusCode

fn from(ctap1: U2FError) -> Self

Converts to this type from the input type.

impl From<U2FError> for u8

fn from(src: U2FError) -> Self

Converts to this type from the input type.

impl Ord for U2FError

fn cmp(&self, other: &U2FError) -> 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 U2FError

fn eq(&self, other: &U2FError) -> 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 U2FError

fn partial_cmp(&self, other: &U2FError) -> 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 TryFrom<u8> for U2FError

type Error = CodeOutOfRange<u8>

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
