Enum ServerConfigError 

pub enum ServerConfigError {
    Unavailable(Box<ConfigurationFetchError>),
    Invalid(ServerConfigurationError),
    Blocked(BlockedConnection),
    Closed,
}

Why resolving, fetching, or storing the server configuration failed.

Variants

Unavailable(Box<ConfigurationFetchError>)

Server configuration unavailable.

The backend did not serve its configuration, or the answer could not be stored. Retryable exactly when the wrapped failure is.

Invalid(ServerConfigurationError)

Server configuration invalid.

The backend published a configuration this client cannot use. Not retryable.

Blocked(BlockedConnection)

The connection is blocked. Not retryable.

Closed

Client is closed.

The client shut down before a deferred configuration check or an explicit refresh finished. Not retryable.

Trait Implementations

impl Debug for ServerConfigError

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

Formats the value using the given formatter.

impl Display for ServerConfigError

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

Formats the value using the given formatter.

impl Error for ServerConfigError

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 ErrorCode for ServerConfigError

fn error_code(&self) -> &'static str

Returns the unique error code for this error.

impl From<BlockedConnection> for ServerConfigError

fn from(source: BlockedConnection) -> ServerConfigError

Converts to this type from the input type.

impl From<ConfigurationFetchError> for ServerConfigError

fn from(error: ConfigurationFetchError) -> ServerConfigError

Converts to this type from the input type.

impl From<ServerConfigError> for ClientError

fn from(error: ServerConfigError) -> Self

Converts to this type from the input type.

impl From<ServerConfigurationError> for ServerConfigError

fn from(source: ServerConfigurationError) -> ServerConfigError

Converts to this type from the input type.

impl RetryableError for ServerConfigError

fn is_retryable(&self) -> bool

fn rate_limit_delay(&self) -> Option<Duration>

The least time to wait before a retry, when the error says so. A rate-limit rejection carries one; [retry_async!] never retries sooner.
