Rust has strict memory safety features that can effectively prevent  memory leaks and wild pointer issues.\n\nFirstly, Rust programs can dynamically allocate memory in heap memory through the `new` keyword or functions such as `malloc` and `calloc`. These functions can allocate memory of any size for the program to use. In Rust, you can use the `free` or `delete` functions to release memory that is no longer in use.\n\nSecondly, ..."}]}],"pr":"ad4014205aefe9c787d69a4a9f841b07baee6acf85eb662d70ab6d0f683d8328"}
