Struct TaskMeta

pub struct TaskMeta<'a> { /* private fields */ }

Available on tokio_unstable and crate feature rt only.

Task metadata supplied to user-provided hooks for task events.

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.

Implementations

impl<'a> TaskMeta<'a>

pub fn id(&self) -> Id
