WorkerLifecycle

Struct WorkerLifecycle 

Source
pub struct WorkerLifecycle {
    state: WorkerState,
    restart_notice_pending: bool,
    ever_ready: bool,
}
Expand description

Tracks worker state plus the one-shot “restarted after crash” notice that must surface EXACTLY once (spec §4: the next call after a crash returns WORKER_RESTARTED once, so the agent knows unsaved edits were lost).

Fields§

§state: WorkerState§restart_notice_pending: bool§ever_ready: bool

True once the worker has completed at least one successful init (reached Ready). A crash during the very first boot loses nothing, so it must NOT arm the WORKER_RESTARTED notice.

Implementations§

Source§

impl WorkerLifecycle

Source

pub fn new() -> Self

Source

pub fn state(&self) -> WorkerState

Source

pub fn on_ready(&mut self) -> Result<(), InvalidTransition>

Successful init handshake: Starting -> Ready.

Source

pub fn on_dispatch(&mut self) -> Result<(), InvalidTransition>

Dispatch a call onto the executor: Ready -> Busy.

Source

pub fn on_complete(&mut self) -> Result<(), InvalidTransition>

Call finished: Busy -> Ready.

Source

pub fn on_crash(&mut self)

Socket closed / process died: transition to Crashed from any state.

Source

pub fn on_respawn(&mut self) -> Result<(), InvalidTransition>

Begin a respawn: Crashed -> Starting, arming the one-shot restart notice.

Source

pub fn take_restart_notice(&mut self) -> bool

Consume the one-shot WORKER_RESTARTED notice; true at most once per crash.
