StatusRespNotMatch

Fields

resp: String

StatusRemoteError

The relay answered a status request with a structured refusal.

retryable is the relay’s own verdict and the reason this is a variant of its own: a caller that loops on every status failure would spin forever on a refusal that reconnecting cannot fix, such as a namespace the credential does not own.

Implementations

impl Error

pub fn remote_retryable(&self) -> Option<bool>

The relay’s verdict on whether the same request could ever succeed, or None when this failure did not come from the relay.

Transport and framing failures are None: nothing about a dropped connection says the relay’s answer is final.

Trait Implementations

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, __snafu_display_formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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 ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
