Struct tokio::task::Id

pub struct Id(_);

Available on crate feature rt and tokio_unstable only.

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.

Note: This is an unstable API. The public API of this type may break in 1.x releases. See the documentation on unstable features for details.

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<Id> for Id

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

This method tests for self and other values to be equal, and is used by ==.

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

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