ROOT::Internal::VecOps::RVecInlineStorageSize< T > Struct Template Reference

template<typename T>
struct ROOT::Internal::VecOps::RVecInlineStorageSize< T >

The size of the inline storage of an RVec.

Our policy is to allocate at least 8 elements (or more if they all fit into one cacheline) unless the size of the buffer with 8 elements would be over a certain maximum size.
