Functions

Function operator==

template <typename T,   typename MR> _CCCL_HOST_DEVICE bool operator==(const allocator< T, MR > & lhs,   const allocator< T, MR > & rhs); Compares the allocators for equality by comparing the underlying memory resources.

Function operator!=

template <typename T,   typename MR> _CCCL_HOST_DEVICE bool operator!=(const allocator< T, MR > & lhs,   const allocator< T, MR > & rhs); Compares the allocators for inequality by comparing the underlying memory resources.
