Struct Watchdog 

pub struct Watchdog { /* private fields */ }

Implementations

impl Watchdog

pub fn new(timeout_secs: u64) -> Self

Create a wall-clock-only watchdog. timeout_secs = 0 disables it. Equivalent to [Watchdog::with_limits(timeout_secs, 0)].

pub fn with_limits(timeout_secs: u64, max_rss_kb: u64) -> Self

Create a watchdog guarding a wall-clock deadline and a resident-memory ceiling. timeout_secs = 0 disables the time guard; max_rss_kb = 0 disables the memory guard. With both 0 this is a no-op handle.

The thread polls cancelled, the deadline, and RSS every poll_interval. On a time breach it exits EXIT_TIMEOUT; on a memory breach, EXIT_OOM. The memory guard is inactive where process_rss_kb returns None (non-Linux); see the module portability note.

pub fn cancel(&self)

Explicitly cancel the watchdog. Idempotent.

Trait Implementations

impl Drop for Watchdog

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
