Rc and Arc implement 1vN ownership mechanism Observe reference count changes one example Multi-threaded powerless Rc Arc The Rust ownership mechanism requires that a value can only have one owner, which is fine in most cases, but consider the following situation: In a graph data structure, multiple edges may own the same node, and the […]

[2023.09.13]: Rust Lang, the inevitable ownership issue
The ownership issue of Rust was skipped when I was learning Rust because I knew it would be difficult to understand without scenarios. Unexpectedly, the scene appeared soon. When developing Yew application components, events and closures are involved, which naturally leads to ownership issues. Without further ado, let’s go directly into the code scene to […]

C++ concurrent programming (5): std::unique_lock, mutex ownership transfer, lock granularity
std::unique_lockflexible locking Reference Blog Sharing data between threads – using mutexes to protect shared data C ++ multi-threaded unique_lock detailed explanation Multithreaded programming (5) – unique_lock Compared with std::lock_guard, std::unqiue_lock is not directly related to the data type of the mutex, so it is more flexible to use It can pass in additional parameters during […]
[c++] Use of std::move ownership transfer
1. Detailed combing of std::move usage ref_frames_ = std::move(ref_frames); cur_frames_ = cur_frames; The advantage of using the std::move function is that the ownership of resources can be transferred from one object to another without the need for a deep copy operation. For variables of smart pointer type, it is also possible to use std::move, and […]
