What optimizations does the Rust compiler make with `loop` versus `while true`?

Question

除了可以推断loop体内设置的未初始化值这一事实之外，还有其他令人信服的理由存在loop吗？

Answer 1

Other than you state your intention, there is no difference. All loops are the same once normalization has happened in the compiler.

See an example of a loop in the Rust playground and the same example with a while true . The assembly generated is exactly the same. The compiler gives a warning for the while true -example to use loop instead.
