Enum BreakerError 

pub enum BreakerError {
    CircuitOpen {
        retry_after_us: u64,
    },
    MaxProbesExceeded,
    ConfigurationError(String),
}

Errors returned by NetworkCircuitBreaker::call.

Variants

CircuitOpen

The circuit is Open; the caller should retry after retry_after_us microseconds.

Fields

retry_after_us: u64

Remaining microseconds before the circuit may transition to HalfOpen.

MaxProbesExceeded

The HalfOpen probe quota is exhausted; this request was rejected without being attempted.

ConfigurationError(String)

An invalid configuration was supplied.

Trait Implementations

impl Clone for BreakerError

fn clone(&self) -> BreakerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BreakerError

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

Formats the value using the given formatter.

impl Display for BreakerError

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

Formats the value using the given formatter.

impl Error for BreakerError

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 BreakerError

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