WebApr 11, 2024 · “Zero-cost abstractions” might sound like a contradiction, but they are real: Rust provides convenient, high-level (i.e., human-understandable) mechanisms for writing code that compiles down to minimal and fast machine code. And it does all this without a Garbage Collector, so you also don’t get unexpected stuttering behaviour. Need more? Webrust-gc. Simple tracing (mark and sweep) garbage collector for Rust. The design and motivation is illustrated in this blog post, with a sketch of the code in this gist. There is another post about the initial design of cgc, its …

WebIf you're using smart pointers, then in order to free the memory associated with A, B & C you need to manually get in there an "break" the circular reference (e.g. using weak_ptr in C++). Garbage collection (typically) works quite differently. Most garbage collectors these days use a reachability test. WebThis situation is very simple to handle with a garbage collector or with manual memory management. Just count the number of B that are using A. However, rust has another way of managing memory via ownership. Does this way of memory management result in another way to handle object A whose (required) lifetime can only be known at runtime? WebJul 28, 2024 · It does not have a garbage collector because it does not need one. Rust has wonderful borrowing and ownership rules that take care of all the memory safety issues.
