Don’t sweat utilizing .clone() to sidestep borrowing (at first)
If you’re writing your first Rust packages, the complexities of possession and borrowing could be dizzying. If all you wish to do is write a easy program that doesn’t should be performant or vastly memory-optimized, Rust’s reminiscence administration might sound intrusive.
This isn’t at all times going to be true; in reality, your development as a Rust developer depends upon studying when reminiscence administration is crucial. However within the very early levels of Rust-dom, whenever you’re nonetheless getting your sea legs contained in the language’s syntax and tooling, that function can really feel like a burden.
One technique to cut back your fear about borrowing—each now and later—is to clone objects moderately than switch possession. Cloning creates a brand new occasion of the identical information however with a brand new, impartial proprietor. The unique occasion retains the unique proprietor, so there are not any points with object possession. And, as with the unique object, the clone will probably be dropped robotically as soon as it goes out of scope.
