Struct PatientGuard 

pub struct PatientGuard { /* private fields */ }

RAII guard returned by ToolCtx::patient.

While held, the kernel’s script-level timeout watchdog is suspended for this execution: the script clock freezes and the guard’s own budget governs instead. Dropping the guard resumes the script clock with the remaining time it had at acquire.

The inner box is the kernel’s hold object; its Drop does the restore. An inert guard (no watchdog running — e.g. the kernel has no script timeout, or a non-kernel test context) holds nothing and drops as a no-op.

Implementations

impl PatientGuard

pub fn inert() -> Self

A guard that does nothing — for contexts without a watchdog.

pub fn held(hold: Box<dyn Any + Send>) -> Self

Wrap a kernel hold object whose Drop restores the watchdog.

pub fn is_active(&self) -> bool

Whether this guard actually suspended a watchdog.
