To quote the Rust book (https://doc.rust-lang.org/book/ch20-01-unsafe-rust.html):

  In addition, unsafe does not mean the code inside the
  block is necessarily dangerous or that it will definitely
  have memory safety problems: the intent is that as the
  programmer, you’ll ensure the code inside an unsafe block
  will access memory in a valid way.

Since you say you already know that much Rust, you can be that programmer!
