Enum AuthenticationError 

#[non_exhaustive]
pub enum AuthenticationError {
    InvalidCredentials,
    UserNotFound,
    SessionExpired,
    InvalidToken,
    TokenExpired,
    NotAuthenticated,
    DatabaseError(String),
    Unknown(String),
}

Authentication errors that can occur during user verification.

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.

InvalidCredentials

The provided credentials (username/password) are incorrect.

UserNotFound

The requested user does not exist.

SessionExpired

The user’s session has expired.

InvalidToken

The provided authentication token is invalid or malformed.

TokenExpired

The JWT token has expired.

NotAuthenticated

The request lacks valid authentication credentials.

DatabaseError(String)

A database error occurred during authentication.

Unknown(String)

An unspecified authentication error.

Trait Implementations

impl Clone for AuthenticationError

fn clone(&self) -> AuthenticationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthenticationError

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

Formats the value using the given formatter.

impl Display for AuthenticationError

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

Formats the value using the given formatter.

impl Eq for AuthenticationError

impl Error for AuthenticationError

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 AuthenticationError

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