Struct DirectNode 

#[repr(C, align(8))]
pub struct DirectNode<'a, V> { /* private fields */ }

direct node descriptor for memory pointer, normally a tiny memory buffer

SAFETY: node operations in immutable by unsafe code, this works because all ops for same node are expected to be ran in a single thread
