Struct ChildTask 

pub struct ChildTask { /* private fields */ }

A handle to a cFE child task.

This is a wrapper around a CFE-level task ID that will automatically call CFE_ES_DeleteChildTask when it goes out of scope, preventing resource leaks. It must not be used for an Application’s Main Task.

Implementations

impl ChildTask

pub fn new( name: &str, entry_point: TaskEntryPoint, stack_ptr: *mut (), stack_size: usize, priority: u16, flags: TaskFlags, ) -> Result<Self>

Creates a new cFE child task and starts it running.

The new task is owned by the calling Application. The stack for the task can be provided or allocated from the system memory heap.

Arguments

• name: A unique string to identify the task.
• entry_point: The function that the new task will execute. This must be a free function with extern "C" linkage.
• stack_ptr: A pointer to the task’s stack, or core::ptr::null_mut() to have cFE allocate it.
• stack_size: The size of the stack to allocate for the new task.
• priority: The priority of the new task (0=highest, 255=lowest).
• flags: Task creation flags (e.g. TaskFlags::FP_ENABLED).

pub fn id(&self) -> TaskId

Returns the underlying TaskId for this child task.

Trait Implementations

impl Debug for ChildTask

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

Formats the value using the given formatter.

impl Drop for ChildTask

fn drop(&mut self)

Deletes the cFE child task when the ChildTask object goes out of scope.
