Enum HealthStatus 

#[non_exhaustive]
pub enum HealthStatus {
    Healthy,
    Degraded(String),
    Unhealthy(String),
}

Health of a single Resource, as reported by Resource::health.

Returned per-resource by Resources::check_all_health and folded into a single worst-case value by Resources::aggregate_health. Health checks are opt-in observability — the engine never calls Resource::health during normal workflow execution.

This enum is #[non_exhaustive]; match it with a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Healthy

The resource is fully operational.

Degraded(String)

The resource is still usable but impaired (e.g. a degraded replica, partial connectivity, elevated latency). The string explains why.

Unhealthy(String)

The resource is not usable. The string explains why.

Implementations

impl HealthStatus

pub fn is_healthy(&self) -> bool

Returns true only for HealthStatus::Healthy.

Trait Implementations

impl Clone for HealthStatus

fn clone(&self) -> HealthStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HealthStatus

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

Formats the value using the given formatter.

impl Eq for HealthStatus

impl PartialEq for HealthStatus

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