Enum CircuitEvent 

pub enum CircuitEvent {
    StateChanged {
        from: String,
        to: String,
        at: u64,
    },
    ThresholdReached {
        failures: u32,
    },
    RecoverySucceeded,
    RecoveryFailed,
}

A notable event emitted by the state machine.

Variants

StateChanged

The circuit transitioned between states.

Fields

from: String

Label of the previous state.

to: String

Label of the new state.

at: u64

Timestamp (µs) at which the transition occurred.

ThresholdReached

The failure rate within the rolling window has reached the threshold.

Fields

failures: u32

Number of failures that triggered the trip.

RecoverySucceeded

Enough probe requests succeeded; the circuit has been closed.

RecoveryFailed

A probe request failed; the circuit has been re-opened.

Trait Implementations

impl Clone for CircuitEvent

fn clone(&self) -> CircuitEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CircuitEvent

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

Formats the value using the given formatter.

impl PartialEq for CircuitEvent

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