Enum ExternalGuardError 

pub enum ExternalGuardError {
    Timeout,
    Transient(String),
    Permanent(String),
}

Errors surfaced from an ExternalGuard call.

Variants

Timeout

The downstream service timed out.

Transient(String)

The downstream service returned a retryable failure (5xx, connection reset, etc.). Retryable errors are counted towards the circuit breaker and may trigger a retry.

Permanent(String)

A permanent error that should not be retried (e.g. malformed request, 4xx auth failure).

Implementations

impl ExternalGuardError

pub fn is_retryable(&self) -> bool

Returns true for errors that should count as a circuit-breaker failure and be retried.

Trait Implementations

impl Debug for ExternalGuardError

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

Formats the value using the given formatter.

impl Display for ExternalGuardError

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

Formats the value using the given formatter.

impl Error for ExternalGuardError

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.
