Кстати вдогонку. Насчет производительности... Так наоборот, на си и плюсах там бОльшие тормоза были, а использование раста позволило по другому надежную архитектуру построить. Вот кусок из ссылки, что недавно скидывали про использование раст в андроиде: "... Safety measures make memory-unsafe languages slow Mobile devices have limited resources and we’re always trying to make better use of them to provide users with a better experience (for example, by optimizing performance, improving battery life, and reducing lag). Using memory unsafe code often means that we have to make tradeoffs between security and performance, such as adding additional sandboxing, sanitizers, runtime mitigations, and hardware protections. Unfortunately, these all negatively impact code size, memory, and performance. Using Rust in Android allows us to optimize both security and system health with fewer compromises. For example, with the new UWB stack we were able to save several megabytes of memory and avoid some IPC latency by running it within an existing process. The new DNS-over-HTTP/3 implementation uses fewer threads to perform the same amount of work by using Rust’s async/await feature to process many tasks on a single thread in a safe manner. ..." https://security.googleblog.com/2022/12/memory-safe-language...
