Struct MetricsScheduler 

pub struct MetricsScheduler<S: ?Sized + Scheduler> { /* private fields */ }

A MetricsScheduler wraps an inner Scheduler and collects metrics about the schedules it’s generating.

Implementations

impl<S: Scheduler> MetricsScheduler<S>

pub fn new(inner: S) -> Self

Create a new MetricsScheduler by wrapping the given Scheduler implementation.

Trait Implementations

impl<S: Debug + ?Sized + Scheduler> Debug for MetricsScheduler<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: ?Sized + Scheduler> Drop for MetricsScheduler<S>

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.

impl<S: Scheduler> Scheduler for MetricsScheduler<S>

fn new_execution(&mut self) -> Option<Schedule>

Inform the Scheduler that a new execution is about to begin. If this function returns None, the test will end rather than performing another execution. If it returns Some(schedule), the returned Schedule can be used to initialize a ReplayScheduler for deterministic replay.

fn next_task( &mut self, runnable_tasks: &[&Task], current_task: Option<TaskId>, is_yielding: bool, ) -> Option<TaskId>

Decide which task to run next, given a list of runnable tasks and the currently running tasks. This method returns Some(task) where task is the runnable task to be executed next; it may also return None, indicating that the execution engine should stop exploring the current schedule.

fn next_u64(&mut self) -> u64

Choose the next u64 value to return to the currently running task.
