Enum RuntimeState 

pub enum RuntimeState {
    Booting,
    Running,
    Stopping,
    Emergency,
}

Runtime lifecycle state.

Represents the current operating mode of the scheduler runtime.

Variants

Booting

Initializing subsystems, loading modules.

Linux equivalent: TASK_NEW

Running

Normal operation, processing events.

Linux equivalent: TASK_RUNNING

Stopping

Graceful shutdown in progress.

Remaining work is drained before full stop.

Linux equivalent: TASK_STOPPED

Emergency

Emergency shutdown (panic recovery mode).

No new work accepted, cleanup only.

Linux equivalent: Kernel oops handling

Implementations

impl RuntimeState

pub const fn is_running(&self) -> bool

Check if runtime is in the running state.

Only in Running state can new work be accepted.

pub const fn is_shutting_down(&self) -> bool

Check if shutdown is in progress.

Returns true for both Stopping and Emergency states.

pub const fn can_accept_work(&self) -> bool

Check if runtime can accept new work.

Equivalent to is_running() - only running runtime accepts work.

pub const fn is_terminal(&self) -> bool

Check if this is a terminal state.

Terminal states indicate the runtime should stop its main loop.

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 Default for RuntimeState

fn default() -> RuntimeState

Returns the “default value” for a type.

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.
