Enum TaskAffinity 

pub enum TaskAffinity {
    Any,
    Worker(usize),
    Prefer(usize),
    MainThread,
}

Affinity specification for a task.

Variants

Any

No affinity — any worker can run this task.

Worker(usize)

Pinned to a specific worker index.

Prefer(usize)

Prefer a worker but allow stealing.

MainThread

Run only on the main thread (worker 0).

Implementations

impl TaskAffinity

pub fn allows(&self, worker: usize) -> bool

Check if a given worker satisfies this affinity.

pub fn is_pinned(&self) -> bool

Whether this is a hard pin (only one worker may run it).

pub fn allows_steal(&self) -> bool

Whether stealing is allowed for this affinity.

Trait Implementations

impl Clone for TaskAffinity

fn clone(&self) -> TaskAffinity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskAffinity

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

Formats the value using the given formatter.

impl Display for TaskAffinity

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

Formats the value using the given formatter.

impl PartialEq for TaskAffinity

fn eq(&self, other: &TaskAffinity) -> 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.
