Struct rio::Completion

pub struct Completion<'a, C: FromCqe> { /* fields omitted */ }

A Future value which may or may not be filled

Safety

To prevent undefined behavior in the form of use-after-free, never allow a Completion's lifetime to end without dropping it. This can happen with std::mem::forget, cycles in Arc or Rc, and in other ways.

Implementations

impl<'a, C: FromCqe> Completion<'a, C>

pub fn wait(self) -> Result<C> where
    C: FromCqe, 

Block on the Completion's completion or dropping of the Filler
