Enum ToolkitError 

pub enum ToolkitError {
    CircuitOpen {
        retry_after: Duration,
    },
    BulkheadClosed,
    RetryExhausted {
        attempts: u32,
    },
}

Errors that can be returned by reliability primitives themselves (as opposed to errors from the wrapped operation).

Variants

CircuitOpen

The circuit breaker is currently open and rejected the call without invoking it.

Fields

retry_after: Duration

How long the breaker expects to remain open.

BulkheadClosed

The bulkhead has been closed and is no longer accepting permits.

RetryExhausted

Retry exhausted its attempt budget without a success.

Fields

attempts: u32

How many attempts were made before giving up.

Trait Implementations

impl Debug for ToolkitError

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

Formats the value using the given formatter.

impl Display for ToolkitError

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

Formats the value using the given formatter.

impl Error for ToolkitError

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.
