Enum FlowExitReason 

#[repr(u8)]
pub enum FlowExitReason {
    Normal = 0,
    Shutdown = 1,
    Killed = 2,
    Fault = 3,
    MailboxOverflow = 4,
    Supervisor = 5,
    Link = 6,
}

Why a flow left the directory. Encoded as Message.payload on system hops.

Named FlowExitReason so it does not collide with the JIT ExitReason (trace-compiler control flow).

Variants

Normal = 0

Shutdown = 1

Reserved: host-wide runtime teardown (not produced today).

Killed = 2

Fault = 3

MailboxOverflow = 4

Reserved: overflow-kill policy (today overflow is MailboxFull / park).

Supervisor = 5

Link = 6

Implementations

impl FlowExitReason

pub fn from_u64(raw: u64) -> Option<Self>

pub fn as_u64(self) -> u64

pub fn is_abnormal(self) -> bool

Abnormal exits propagate through links (BEAM: normal does not).

Shutdown / Killed / Supervisor are host-policy reasons; they still count as abnormal so a supervisor abort is not silently swallowed by links.
