Struct MonitorContext 

pub struct MonitorContext { /* private fields */ }

A handle to the monitor which allows probing Shared context for the monitor, providing access to the shutdown handle and the set of workers it supervises.

Implementations

impl MonitorContext

pub fn workers(&self) -> &Vec<WorkerContext>

Returns a reference to all workers managed by this monitor.

pub fn shutdown(&self) -> Result<(), MonitorError>

Initiates a shutdown of the monitor.

This signals the shutdown handle but does not block waiting for workers to finish.

pub fn resume_worker(&self, name: &str) -> Result<(), WorkerError>

Resumes the worker with the given name.

Errors

Returns WorkerError if no worker with name exists, or if the resume itself fails.

pub fn pause_worker(&self, name: &str) -> Result<(), WorkerError>

Pauses the worker with the given name.

Errors

Returns WorkerError if no worker with name exists, or if pausing fails.

pub fn stop_worker(&self, name: &str) -> Result<(), WorkerError>

Stops the worker with the given name.

Errors

Returns WorkerError if no worker with name exists, or if stopping fails.

pub fn wake_worker(&self, name: &str) -> Result<(), WorkerError>

Wakes the worker with the given name.

Errors

Returns WorkerError if no worker with name exists.

pub fn get_worker(&self, name: &str) -> Result<&WorkerContext, WorkerError>

Looks up a worker by name.

Errors

Returns WorkerError::StateError if no worker with name exists among the managed workers.

pub fn cancel_task( &self, worker: &str, task_id: &str, ) -> Result<(), BoxDynError>

Available on crate feature task-context only.
