Expand description

A thread panic monitor.

Implementations§

source§

impl ThreadMonitor

source

pub fn new() -> Self

Instantiates a new thread monitor.

source

pub fn init(&'static self) -> Result<()>

Initializes the thread monitor.

This should be done before watching any threads.

Internally, the monitor will set up a new panic hook, which will be used for detecting panics on the threads being watched.

The monitor will initially ignore all panics. Use set_watched or watch to specify which threads to monitor.

source

pub fn set_watched(&self, thread_ids: HashSet<ThreadId>) -> Result<()>

Set the threads to be watched by this monitor.

If ThreadMonitor::init has been called, the monitor will begin recording panics for the specified threads.

source

pub fn watch( &self, thread_ids: Option<&HashSet<ThreadId>>, ) -> Result<Vec<Thread>>

Watches the provided thread IDs.

ThreadMonitor::init has to be called before this method. An Uninitialized error will be returned if it’s not.

  • If an empty set is passed, this function returns immediately.
  • If a thread set is not passed and one hasn’t been set with set_watched, a NoWatches error will be returned.
  • If set_watched was previously called and one of the watched threads already panicked, this function will return immediately.
  • Otherwise, the monitor will block the current thread until one of the watched threads has a panic.
