WebApr 6, 2024 · Conclusion: In summary, a custom assignment operator in C++ can be useful in cases where the default operator is insufficient or when resource management, memory allocation, or inheritance requires special attention. It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states. WebI mean zero-overhead abstractions generally imply zero runtime overhead. But it's like that because C++ wasn't made thinking about those features from the ground up, so the backwards compatibility makes it impossible for it to be zero cost.

Let’s discuss some of the major differences: 1. Move semantics Moving constructor results in invalid objects with unspecified states, causing errors due to using a moving object. After an object has been moved in Rust, its state is changed to unusable by the static analyzer (built-in).
