Enum AuthError 

pub enum AuthError {
    KeyNotFound(String),
    InvalidSignature {
        key_id: String,
        expected: u64,
        got: u64,
    },
    ReplayDetected(u64),

    NonceExhausted,
    InvalidSequence {
        expected: u64,
        got: u64,
    },
}

All errors that can be returned by MessageAuthenticator.

Variants

KeyNotFound(String)

A key with the given ID does not exist in the keystore.

InvalidSignature

The recomputed signature did not match the one supplied in the message.

Fields

key_id: String

Key ID associated with the failing verification.

expected: u64

The signature that the verifier computed.

got: u64

The signature that was present in the message.

ReplayDetected(u64)

The nonce in a message was found in the replay window.

KeyExpired(String)

The key has passed its expiry timestamp.

NonceExhausted

The PRNG state has been exhausted (state reached zero).

InvalidSequence

A SequentialNonce policy violation: the sequence number jumped or regressed unexpectedly.

Fields

expected: u64

The next expected sequence number.

got: u64

The sequence number that was actually present.

Trait Implementations

impl Debug for AuthError

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

Formats the value using the given formatter.

impl Display for AuthError

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

Formats the value using the given formatter.

impl Error for AuthError

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.
