Struct HealthRegistry 

pub struct HealthRegistry { /* private fields */ }

Active health state shared by one or more BackendViews.

Registries use full backend identity by default. Callers can supply an equivalence key to intentionally share probes across backend variants.

Implementations

impl HealthRegistry

pub fn new() -> Self

Create an empty registry keyed by full backend identity.

pub fn with_equivalence( equivalence_key: impl Fn(&Backend) -> u64 + Send + Sync + 'static, ) -> Self

Create an empty registry using equivalence_key to group targets.

Backends that produce the same u64 key share one health state and probe. Callers are responsible for ensuring that backends which need independent health state produce distinct keys.

pub fn set_health_check(&self, hc: Box<dyn HealthCheck + Send + Sync + 'static>)

Set the health-check implementation used by every view in this registry.

Panics

Panics if a health check has already been set.

pub fn target_count(&self) -> usize

Return the number of distinct backend targets currently being tracked.

Targets that produce the same registry health key count as one target.

pub async fn run_health_check(&self, parallel: bool)

Run one active health-check pass over the union of all registered views.

When parallel is true, all targets are checked concurrently.

Dropping the returned future cancels the pass: outstanding per-target checks are aborted rather than left running to completion, so targets not yet reported keep their previous health.

Trait Implementations

impl Default for HealthRegistry

fn default() -> Self

Returns the “default value” for a type.
