Enum Error 

#[non_exhaustive]
pub enum Error {
    SecretTooShort {
        actual: usize,
        minimum: usize,
    },
    InvalidDigits {
        actual: u8,
    },
    ZeroPeriod,
    TimestampBeforeEpoch {
        timestamp: u64,
        epoch: u64,
    },
}

An error in an HOTP or TOTP system parameter.

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.

SecretTooShort

The shared secret is shorter than RFC 4226 permits.

Fields

actual: usize

Length supplied by the caller, in bytes.

minimum: usize

Minimum accepted length, in bytes.

InvalidDigits

The requested decimal code width is outside the RFC-defined range.

Fields

actual: u8

Width supplied by the caller.

ZeroPeriod

A zero-second TOTP period was requested.

TimestampBeforeEpoch

The supplied Unix timestamp precedes the configured TOTP epoch.

Fields

timestamp: u64

Timestamp supplied by the caller.

epoch: u64

Configured initial timestamp (T0).

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 Copy for Error

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 Eq for Error

impl Error for Error

Available on crate feature std only.

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 VerifyError

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
