Struct alloc::task::LocalTaskObj

pub struct LocalTaskObj { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (futures_api #50547)

futures in libcore are unstable

A custom trait object for polling tasks, roughly akin to Box<Future<Output = ()>>. Contrary to TaskObj, LocalTaskObj does not have a Send bound.

Methods

impl LocalTaskObj

pub fn new<T>(t: T) -> LocalTaskObj where     T: UnsafeTask,

🔬 This is a nightly-only experimental API. (futures_api #50547)

futures in libcore are unstable

Create a LocalTaskObj from a custom trait object representation.

pub unsafe fn as_task_obj(self) -> TaskObj

Converts the LocalTaskObj into a TaskObj To make this operation safe one has to ensure that the UnsafeTask instance from which this LocalTaskObj was created actually implements Send.
