Struct Shared 

pub struct Shared {
    pub auth: Auth,
    pub limits: LimitsConfig,
    pub loopback_hosts_only: bool,
    pub ready: Arc<AtomicBool>,
    pub app: OnceLock<Arc<AppState>>,
    pub stop: CancellationToken,
}

State that exists for the whole process lifetime, including while standing by.

Fields

auth: Auth

Credentials.

limits: LimitsConfig

Request limits.

loopback_hosts_only: bool

Running without auth on loopback: HTTP requests must name a loopback host, so a web page cannot reach the API by rebinding its own name to 127.0.0.1.

ready: Arc<AtomicBool>

True while this instance is the leader and serving.

app: OnceLock<Arc<AppState>>

Set once leadership is acquired and the scheduler is running.

stop: CancellationToken

Cancelled when the server stops serving (ends Watch streams, listeners).

Implementations

impl Shared

pub fn app(&self) -> Option<&Arc<AppState>>

The serving state, or None while standing by (or after stopping).

pub fn is_standby(&self) -> bool

Running and not leading: waiting for leadership, or deposed. False while shutting down.

pub fn app_or_unavailable(&self) -> Result<&Arc<AppState>, Status>

The serving state as a gRPC result.
