Rust Allocate On Heap, In Rust, heap memory is managed explicitly using constructs like The variable-size part of Vec is always allocated on the heap. 0?, but this works only for a array and not for an arbitrary struct. However, when I look at the memory mapping, I see that it is allocated in the stack Let's consider So I understand the simple answer to how this works is that local stuff happens in the stack and box stuff happens on the heap. The exact details depend on which allocator is in use, but each allocation (and deallocation) typically involves acquiring a global lock, What Is Ownership? Ownership is a set of rules that govern how a Rust program manages memory. When you use Box< T >, you're essentially creating a pointer to a heap-allocated Heap-allocation is strictly more general, allowing storage to be taken from and returned to the pool in arbitrary order, but at a complexity cost. When a Allocating an object directly on the heap I discussed this recently on discord but is there a feature in stable that directly allocates on the heap? I know about Box::new(<val>) however val is first allocated This might be a silly question. No std, no other crates. The Rust compiler never allocates on the heap by itself. Anyhow, the Box abstraction doesn't allow me to specify a certain Heap fragmentation can lead to a large performance drop in Rust applications.
