Enum SignalPolicy 

pub enum SignalPolicy {
    Off,
    CtrlC,
    CtrlCAndTerm,
}

Which signals trigger an automatic export before termination.

The policy is consulted by the signal-installing layer (module 2); this type only carries the user’s intent so the wiring code can decide which handlers to register. Keeping it as a plain enum (rather than a bitfield) makes the supported combinations explicit and exhaustive.

Variants

Off

No signal handler installed. Only Drop + panic-hook cover exit paths.

CtrlC

Catch SIGINT (Ctrl-C) only. This is the default policy.

CtrlCAndTerm

Catch both SIGINT and SIGTERM.

Current limitation

SIGTERM is NOT yet wired up — only SIGINT is caught by the underlying ctrlc crate. SIGTERM support requires signal_hook (or a raw libc handler) and will be added when that dependency is approved. Selecting this policy currently behaves identically to SignalPolicy::CtrlC from the perspective of which signals actually trigger an export.
