Enum HealthState 

pub enum HealthState {
    Healthy,
    Degraded,
    Unavailable,
    Recovering,
}

Health state of a single CA backend (RHELBU-3536 R4).

Transitions follow the state machine:

Healthy -> Degraded -> Unavailable -> Recovering -> Healthy
               ^                          |
               +---- (probe failure) ------+

Variants

Healthy

CA is responding normally within latency thresholds.

Degraded

CA is responding but with elevated latency or intermittent errors.

Unavailable

CA is not responding; circuit breaker is open.

Recovering

CA was unavailable and is being re-probed after cooldown.

Implementations

impl HealthState

pub fn is_available(&self) -> bool

Whether this state allows routing requests to the CA.

Trait Implementations

impl Clone for HealthState

fn clone(&self) -> HealthState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HealthState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HealthState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HealthState

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

impl Serialize for HealthState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
