Enum AuthError 

#[non_exhaustive]
pub enum AuthError {
    InvalidCredentials(String),
    AuthenticationFailed(String),
    TokenExpired,
    TokenAcquisition(String),
    UnsupportedMethod(String),
    Sspi(String),
    Certificate(String),
    Network(String),
    Configuration(String),
    AzureIdentity(String),
}

Errors that can occur during authentication.

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(String)

Invalid credentials provided.

AuthenticationFailed(String)

Authentication failed on server.

TokenExpired

Token expired or invalid.

TokenAcquisition(String)

Token acquisition failed.

UnsupportedMethod(String)

Unsupported authentication method.

Sspi(String)

SSPI/GSSAPI error.

Certificate(String)

Certificate error.

Network(String)

Network error during authentication.

Configuration(String)

Configuration error.

AzureIdentity(String)

Azure identity error.

Implementations

impl AuthError

pub fn is_transient(&self) -> bool

Check if this error is transient and may succeed on retry.

Network errors, token acquisition failures (may be temporary service issues), and Azure identity errors are potentially transient. Invalid credentials and unsupported methods are terminal.

pub fn is_terminal(&self) -> bool

Check if this error is terminal and will never succeed on retry.

Invalid credentials, unsupported methods, certificate errors, and configuration errors are permanent.

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.
