Enum TerminateError

pub enum TerminateError<TerminalStatus> {
    Unsupported,
    AlreadyTerminated(TerminalStatus),
    ChannelClosed,
    Io(Error),
}

Error returned by ProcHandle::terminate and ProcHandle::kill.

• Unsupported: the manager cannot perform the requested proc signaling (e.g., local/in-process manager that doesn’t emulate kill).
• AlreadyTerminated(term): the proc was already terminal; term is the same value wait() would return.
• ChannelClosed: the manager lost its lifecycle channel and cannot reliably observe state transitions.
• Io(err): manager-specific failure delivering the signal or performing shutdown (e.g., OS error on kill).

Variants

Unsupported

Manager doesn’t support signaling (e.g., Local manager).

AlreadyTerminated(TerminalStatus)

A terminal state was already reached while attempting terminate/kill.

ChannelClosed

Implementation lost its status channel / cannot observe state.

Io(Error)

Manager-specific failure to deliver signal or perform shutdown.
