Yeah, to quote the manual:

"[Unsafe Rust allows you to]

• Dereference a raw pointer.
• Call an unsafe function or method.
• Access or modify a mutable static variable.
• Implement an unsafe trait.
• Access fields of unions.

[…] The unsafe keyword only gives you access to these five features that are then not checked by the compiler for memory safety."
