Detailed Description

template<typename T>
class uni20::cuda::WriteAccess< T >

Scoped read/write access to a CUDA buffer on one stream.

The constructor installs predecessor waits on the stream. The destructor records an exclusive-writer completion at the current stream tail and publishes it back to the buffer.
