Struct Manager_type

pub struct Manager_type(/* private fields */);

A manager for tasks.

Implementations

impl Manager_type

pub const Root_task_identifier: Task_identifier_type = _

pub unsafe fn Register_task(&self) -> Result_type<()>

Register the current thread as a task.

This function should ONLY be called for testing purposes.

Safety

This function is unsafe because it can lead to undefined behavior if the current thread is already registered.

pub fn Get_thread_name(&self) -> Option<String>

pub fn Get_task_name( &self, Task_identifier: Task_identifier_type, ) -> Result_type<String>

Arguments

• Task_identifier - The identifier of the task.

pub fn New_thread_internal<T, F>( Parent_task_identifier: Task_identifier_type, Name: &str, Stack_size: Option<usize>, Function: F, Main_thread: bool, ) -> Result_type<Join_handle_type<T>>

where T: Send + 'static, F: FnOnce() -> T + Send + 'static,

pub fn New_thread<T, F>( &self, Parent_task_identifier: Task_identifier_type, Name: &str, Stack_size: Option<usize>, Function: F, ) -> Result_type<Join_handle_type<T>>

where T: Send + 'static, F: FnOnce() -> T + Send + 'static,

Create a new thread, returns the identifier of the thread.

This function checks if the parent task exists.

pub fn Sleep(Duration: Duration)

Sleep the current thread for a given duration.

pub fn New_task<T, F>( &self, Parent_task_identifier: Task_identifier_type, Name: &str, Stack_size: Option<usize>, Function: F, ) -> Result_type<(Task_identifier_type, Join_handle_type<T>)>

where T: Send + 'static, F: FnOnce() -> T + Send + 'static,

Create a new child task, returns the identifier of the child task.

Arguments

• Parent_task_identifier - The identifier of the parent task, if None, the current task is used.
• Owner - The identifier of the user that owns the task, if None, the parent task owner is used.
• Name - The human readable name of the task.
• Stack_size - The size of the stack of the task.
• Function - The function that the task will execute.

pub fn Get_child_tasks( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Vec<Task_identifier_type>>

Get the children tasks of a task.

pub fn Get_parent_task( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Task_identifier_type>

Get the parent task of a task.

pub fn Set_user( &self, Task_identifier: Task_identifier_type, User: User_identifier_type, ) -> Result_type<()>

pub fn Set_group( &self, Task_identifier: Task_identifier_type, Group: Group_identifier_type, ) -> Result_type<()>

pub fn Get_children_threads( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Vec<Thread_identifier_type>>

Get the children threads of a task.

pub fn Get_user( &self, Task_identifier: Task_identifier_type, ) -> Result_type<User_identifier_type>

Get user identifier of the owner of a task.

pub fn Get_group( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Group_identifier_type>

Get group identifier of the owner of a task.

pub fn Get_current_thread_identifier(&self) -> Thread_identifier_type

pub fn Get_current_task_identifier(&self) -> Result_type<Task_identifier_type>

pub fn Get_environment_variable( &self, Task_identifier: Task_identifier_type, Name: &str, ) -> Result_type<Environment_variable_type>

pub fn Get_environment_variables( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Vec<Environment_variable_type>>

pub fn Set_environment_variable( &self, Task_identifier: Task_identifier_type, Name: &str, Value: &str, ) -> Result_type<()>

pub fn Remove_environment_variable( &self, Task_identifier: Task_identifier_type, Name: &str, ) -> Result_type<()>

pub fn Pop_signal( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Option<Signal_type>>

pub fn Peek_signal( &self, Task_identifier: Task_identifier_type, ) -> Result_type<Option<Signal_type>>
