Struct TaskManager 

Source 
pub struct TaskManager {
    tasks: HashMap<TaskId, RunningTask>,
}
Expand description

Manages the lifecycle of background tasks.

The task manager spawns tasks in dedicated threads and provides methods to stop individual tasks or all tasks at once.

Fields§

§tasks: HashMap<TaskId, RunningTask>

Implementations§

Source§

impl TaskManager

Source

pub fn new() -> Self

Creates a new empty task manager.

Source

pub fn start( &mut self, task: Box<dyn BackgroundTask>, hub: Sender<Event>, ) -> Result<TaskId, TaskError>

Starts a background task in a new thread.

The task receives a clone of hub for sending events and a ShutdownSignal for graceful termination.

Returns an error if a task with the same ID is already running.

Source

pub fn stop(&mut self, id: &TaskId) -> Result<(), TaskError>

Stops a running task by ID.

Sends the shutdown signal and waits for the task thread to finish. Returns an error if the task is not running.

Source

pub fn stop_all(&mut self)

Stops all running tasks.

Sends shutdown signals to all tasks and waits for them to finish.

Source

fn cleanup_finished(&mut self)

Removes entries for tasks whose threads have finished.

Source

pub fn is_running(&mut self, id: &TaskId) -> bool

Returns true if a task with the given ID is running.

Source

pub fn running_tasks(&mut self) -> Vec<TaskId>

Returns the IDs of all running tasks.
