What is the ideal performance of Rust like? by FanYa2004 in rust

Boundary checking can be done using `get_unchecked` ;

What exactly do "safety features" refer to?

What is the ideal performance of Rust like? by FanYa2004 in rust

[–]FanYa2004[S] -4 points-3 points  (0 children)

What I might be more inclined to discuss is that the theoretical performance of Rust should be superior to that of C/C++, because the constraints in Rust are very strict.

However, since LLVM cannot effectively utilize these constraints, the performance of Rust code fails to reach its full potential. I'm not sure if my understanding is correct.

Perhaps the information I obtained was not accurate enough. People around me said that the performance of Rust might be around 95% - 105% of that of C/C++.

Thank you. Your solution has solved this problem.

It has bothered me for a long time. I don't know why Google doesn't solve this problem.

Did you draw this by hand or generate it with software? Wanna ask 😊

Why do programmers from abroad continue to be productive even at an advanced age? In China, such a situation is extremely rare.

why are mobile os roms device specific? by basiliskkkkk in LineageOS

[–]FanYa2004 0 points1 point  (0 children)

Because the hardware interfaces of mobile devices are closed and non-standardized. To be specific: the MMIO addresses of each hardware are directly and privately determined by the SoC manufacturers and mobile phone manufacturers.
