Detailed Description

template<class T, MemSpace M>
class celeritas::Copier< T, M >

Copy spans of data.

The destination (which can be a reusable buffer) is the constructor argument, and the source of the data to copy is the function argument.

Example of copying data from device to host:

Copier copy_to_host{ObserverPtr<int, MemSpace::host>{host_ints.data()},
                    host_ints.size(),
                    StreamId{}};
copy_to_host(MemSpace::device, device_ints);
