Struct vector::sinks::prelude::future::LocalFutureObj

pub struct LocalFutureObj<'a, T> { /* private fields */ }

Expand description

A custom trait object for polling futures, roughly akin to Box<dyn Future<Output = T> + 'a>.

This custom trait object was introduced as currently it is not possible to take dyn Trait by value and Box<dyn Trait> is not available in no_std contexts.

Implementations§

impl<'a, T> LocalFutureObj<'a, T>

pub fn new<F>(f: F) -> LocalFutureObj<'a, T> ⓘ
where F: UnsafeFutureObj<'a, T> + 'a,

Create a LocalFutureObj from a custom trait object representation.

pub unsafe fn into_future_obj(self) -> FutureObj<'a, T> ⓘ

Converts the LocalFutureObj into a FutureObj.

§Safety

To make this operation safe one has to ensure that the UnsafeFutureObj instance from which this LocalFutureObj was created actually implements Send.
