It is better to think of Rust having explicit memory management, rather than manual memory management. C/C++ has manual memory management: the burden is on you to do it correctly. If you fuck up, your program will have bugs. Rust requires that your code be explicit about memory issues, but the compiler works with you to achieve that. if your code compiles it is correct; if it doesn't compile, the error points out what needs to be fixed. When I write Rust it rarely feels like I am taking on that burden myself.
