Struct TaskId

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

A unique identifier for a running task.

A TaskId is an opaque object that uniquely identifies each task created during the lifetime of a program. TaskIdss are guaranteed not to be reused, even when a task terminates. A TaskId can be retrieved from the TaskRef::id, JoinHandle::id, and Task::id methods.

A TaskId does not increase the reference count of the task it references, and task IDs may persist even after the task they identify has completed and been deallocated.

Trait Implementations

impl Clone for TaskId

fn clone(&self) -> TaskId

Returns a copy 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 Display for TaskId

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

Formats the value using the given formatter.

impl Hash for TaskId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for TaskId

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

Formats the value using the given formatter.

impl<T> PartialEq<&JoinHandle<T>> for TaskId

fn eq(&self, other: &&JoinHandle<T>) -> 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.

impl<T> PartialEq<&TaskId> for JoinHandle<T>

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.

impl PartialEq<&TaskId> for TaskId

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

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

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