Unsafe Rust

An unsafe block doesn't turn the borrow checker off. Everything inside it is still checked the normal way; it only unlocks five extra abilities the compiler can't verify on its own

• Dereference a raw pointer, *const T or *mut T
• Call an unsafe function or method, including functions from C
• Read or write a static mut
• Implement an unsafe trait such as Send or Sync
• Read the fields of a union
