Struct Watchdog 

pub struct Watchdog { /* private fields */ }

A hard --timeout bound for a self-contained (non-child-running) tool.

arm spawns a thread that, once the limit passes, prints <tool>: timed out after <limit>; aborted to stderr and exits the process with status 2 (the suite’s usage/runtime-error code). Dropping the guard — or calling disarm — defuses it, so a run that finishes in time (or is about to start un-interruptible work, like ct-edit’s write phase) is never killed.

Implementations

impl Watchdog

pub fn arm(tool: &'static str, limit: Duration) -> Watchdog

Arm a timeout for tool; the returned guard must stay alive while the bound should be enforced.

pub fn disarm(&self)

Defuse the watchdog; after this the limit is never enforced.

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.
