Enum RuntimeState 

#[non_exhaustive]
pub enum RuntimeState {
    Initializing,
    Idle,
    Running,
    Recovering,
    Retired,
    Stopped,
    Destroyed,
}

The state of a runtime instance.

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.

Initializing

Initializing (first state after creation).

Idle

Idle — no run in progress, ready to accept input.

Running

A run is in progress.

Recovering

Recovering from a crash or error.

Retired

Retired — no longer accepting new input, draining existing.

Stopped

Permanently stopped (terminal).

Destroyed

Destroyed (terminal).

Implementations

impl RuntimeState

pub fn is_terminal(&self) -> bool

Check if this is a terminal state.

pub fn can_accept_input(&self) -> bool

Check if the runtime can accept new input in this state.

pub fn can_process_queue(&self) -> bool

Check if the runtime can process queued inputs in this state.

Retired runtimes can still drain their queue but cannot accept new input.

pub fn can_transition_to(&self, next: &RuntimeState) -> bool

Validate a transition from this state to another (§22 table).

pub fn transition( &mut self, next: RuntimeState, ) -> Result<(), RuntimeStateTransitionError>

Attempt to transition, returning an error if invalid.

Trait Implementations

impl Clone for RuntimeState

fn clone(&self) -> RuntimeState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RuntimeState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RuntimeState

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

Formats the value using the given formatter.

impl Hash for RuntimeState

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 RuntimeState

fn eq(&self, other: &RuntimeState) -> 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 RuntimeState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RuntimeState

impl Eq for RuntimeState

impl StructuralPartialEq for RuntimeState
