Enum SingletonState 

#[non_exhaustive]
pub enum SingletonState {
    Inactive,
    Starting,
    Active {
        ref_: UntypedActorRef,
        here: bool,
    },
    HandingOver,
}

Singleton lifecycle state.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Inactive

No singleton known yet.

Starting

We are about to become the singleton, but haven’t started it.

Active

The singleton lives at this ref.

Fields

ref_: UntypedActorRef

here: bool

HandingOver

We were the singleton; new oldest member is taking over.

Trait Implementations

impl Clone for SingletonState

fn clone(&self) -> SingletonState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SingletonState

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

Formats the value using the given formatter.

impl PartialEq for SingletonState

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