Struct TaskId 

#[repr(transparent)]
pub struct TaskId(pub u32);

A type-safe, zero-cost wrapper for an OSAL Task ID.

Tuple Fields

0: u32

Implementations

impl TaskId

pub fn set_priority(&self, priority: u8) -> Result<()>

Sets the priority of this task.

Arguments

• priority: The new priority (0=highest, 255=lowest).

pub fn current() -> Result<Self>

Retrieves the TaskId of the currently executing task.

pub fn index(&self) -> Result<u32>

Returns a zero-based index for this task, suitable for indexing into a user-provided per-task context array.

This is the workaround for OSAL not supporting per-task arguments (see nasa/osal#1394). Usage:

static CONTEXTS: [AtomicPtr<()>; 16] = /* ... */;

// At task creation:
let task = Task::new("worker", worker_entry, ...)?;
CONTEXTS[task.id().index()? as usize].store(ctx_ptr, Ordering::Release);

// Inside the task:
let idx = TaskId::current()?.index()? as usize;
let ctx = CONTEXTS[idx].load(Ordering::Acquire);

pub fn current_index() -> Result<u32>

Shorthand: get the current task’s zero-based index.

pub fn from_name(name: &str) -> Result<Self>

Finds an existing OSAL task ID by its name.

Trait Implementations

impl Clone for TaskId

fn clone(&self) -> TaskId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskId

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

Formats the value using the given formatter.

impl PartialEq for TaskId

fn eq(&self, other: &TaskId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
