Enum ProcessState 

pub enum ProcessState {
    Spawning,
    Running,
    Exited {
        code: i32,
    },
}

Lifecycle of a single process the launcher knows about. The reducer transitions through these in order — there’s no skipping (Spawning → Running → Exited).

Variants

Spawning

Spawn issued; child handle returned but process hasn’t confirmed it’s alive yet. In B.3 we transition straight to Running on Register because that’s the first authoritative signal. B.4+ adds intermediate state for “spawned but not yet registered.” F.7 cleanup audit: the variant is reserved for that future intermediate state; keep with allow rather than delete to preserve the documented state machine shape.

Running

Process has registered with the launcher and is doing its work. Healthy.

Exited

Process exited (clean Goodbye → code=0, crash → non-zero).

Fields

code: i32

Trait Implementations

impl Clone for ProcessState

fn clone(&self) -> ProcessState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessState

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

Formats the value using the given formatter.

impl PartialEq for ProcessState

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