Struct HealthCheckRegistry 

pub struct HealthCheckRegistry { /* private fields */ }

Registry of health checks.

Collects named health checks that can be evaluated together to produce a HealthReport.

Example

let mut registry = HealthCheckRegistry::new();

// Critical check — failure makes the app "unhealthy"
registry.add("database", true, || async {
    // db.ping().await?;
    Ok(())
});

// Non-critical check — failure makes the app "degraded"
registry.add("cache", false, || async {
    // cache.ping().await?;
    Ok(())
});

Implementations

impl HealthCheckRegistry

pub fn new() -> Self

Create a new empty registry.

pub fn add<F, Fut>( &mut self, name: impl Into<String>, critical: bool, check_fn: F, )

where F: Fn() -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<(), String>> + Send + 'static,

Add a named health check.

Parameters

• name: Identifier for the check (e.g., “database”, “cache”).
• critical: If true, failure of this check makes the overall status Unhealthy. If false, failure makes it Degraded (unless another critical check fails).
• check_fn: Async function that returns Ok(()) on success or Err(message) on failure.

pub async fn check_all(&self) -> HealthReport

Run all health checks and produce a report.

pub fn len(&self) -> usize

Returns the number of registered checks.

pub fn is_empty(&self) -> bool

Returns true if no checks are registered.
