 When comparing raw pointers they are compared by their address, rather than by what they point to.
 When comparing raw pointers to [dynamically sized types] they also have their additional data compared.
 
+Raw pointers can be created directly using [`core::ptr::addr_of!`] for `*const` pointers and [`core::ptr::addr_of_mut!`] for `*mut` pointers.

 ## Smart Pointers
 
 The standard library contains additional 'smart pointer' types beyond references and raw pointers.
