Detailed Description

template<Kokkos::ExecutionSpace Exec>
struct Kokkos::Execution::ExecutionSpaceImpl::ExecutionSpaceRef< Exec >

Wrap a Kokkos execution space to make it cheap to copy/move in new environments.

Warning

It does not extend the lifetime of the execution space instance (it does not own it).
