Struct Id

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

An opaque ID that uniquely identifies a task relative to all other currently running tasks.

Notes

• Task IDs are unique relative to other currently running tasks. When a task completes, the same ID may be used for another task.
• Task IDs are not sequential, and do not indicate the order in which tasks are spawned, what runtime a task is spawned on, or any other data.
• The task ID of the currently running task can be obtained from inside the task via the task::try_id() and task::id() functions and from outside the task via the JoinHandle::id() function.

Trait Implementations

impl Clone for Id

fn clone(&self) -> Id

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Id

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

Formats the value using the given formatter.

impl Display for Id

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

Formats the value using the given formatter.

impl Hash for Id

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 PartialEq for Id

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