Struct HealthService 

pub struct HealthService { /* private fields */ }

Health service wrapper for xDS server.

Provides gRPC health checking protocol support with service-level health status management.

Implementations

impl HealthService

pub fn new() -> (Self, HealthServer<impl Health>)

Create a new health service and return both the wrapper and the tonic service.

The returned tuple contains:

• HealthService - wrapper for managing health status
• The health server that can be added to a tonic router

pub async fn set_serving(&self, service_name: &str)

Set a service as serving (healthy).

pub async fn set_not_serving(&self, service_name: &str)

Set a service as not serving (unhealthy).

pub async fn set_unknown(&self, service_name: &str)

Set a service status to unknown.

pub async fn set_all_serving(&self)

Set all xDS services as serving.

pub async fn set_all_not_serving(&self)

Set all xDS services as not serving (for graceful shutdown).

pub const fn xds_service_names() -> &'static [&'static str]

Get the list of xDS service names for health checking.

This returns the standard Envoy xDS service names plus a generic “xds” entry. These names match the gRPC service names used by Envoy clients.
