Enum ShutdownState 

pub enum ShutdownState<P, N> {
    AwaitingPlan,
    AwaitingPlanAfterShutdown,
    Ready {
        plan: P,
    },
    Stopping {
        plan: P,
        phase: usize,
        awaiting: Vec<N>,
    },
    Completed,
}

Complete phase of coordinated shutdown, including plan installation.

The installed plan remains owned by the exact phase in which it is valid. A shutdown request received before installation has its own state and is discharged immediately when a plan later arrives. No correlated readiness flag or optional plan can describe a contradictory combination.

Variants

AwaitingPlan

Child establishment has not yet produced the plan.

AwaitingPlanAfterShutdown

Shutdown was requested while child establishment was incomplete.

Ready

The validated plan is installed and shutdown has not been requested.

Fields

plan: P

Stopping

One plan phase is active and owns its outstanding child IDs.

Fields

plan: P

phase: usize

awaiting: Vec<N>

Completed

Every configured phase completed, or the installed plan was empty.

Trait Implementations

impl<P: Clone, N: Clone> Clone for ShutdownState<P, N>

fn clone(&self) -> ShutdownState<P, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P: Debug, N: Debug> Debug for ShutdownState<P, N>

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

Formats the value using the given formatter.

impl<P: PartialEq, N: PartialEq> PartialEq for ShutdownState<P, N>

fn eq(&self, other: &ShutdownState<P, N>) -> 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.
