Enum ServicePhase 

pub enum ServicePhase {
    Starting,
    Running,
    BackingOff,
    Stopping,
    Terminated,
}

Lifecycle phase of a supervised service.

This is a plain enum without associated data; the richer context (timing, error info, attempt counts) lives in ServiceLifecycle.

Variants

Starting

The service is initializing (connecting to databases, setting up channels, etc.).

Running

The service’s main run() loop is executing.

BackingOff

The service failed and is waiting for the backoff timer to expire before the supervisor attempts a restart.

Stopping

A shutdown signal was received; the service is performing cleanup.

Terminated

Terminal state — the service has exited. No further transitions are valid.

Implementations

impl ServicePhase

pub fn is_terminal(&self) -> bool

Returns true if the service is in a terminal state and will not transition again.

pub fn is_alive(&self) -> bool

Returns true if the service is considered “alive” (starting, running, or backing off for a retry).

Trait Implementations

impl Clone for ServicePhase

fn clone(&self) -> ServicePhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServicePhase

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServicePhase

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ServicePhase

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

Formats the value using the given formatter.

impl Hash for ServicePhase

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ServicePhase

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

impl Serialize for ServicePhase

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
