Question regarding a section in lifetimes about learning-rust.github.io HOT 3 CLOSED

Actually the statement is correct. At compile time rustc checks the lifetime annotations. Lifetimes allows for safe memory management at runtime. Basically at compile time it checks if a variable will be used afterwards or can be fred after for instance exiting a function. According to that "plan", at runtime the variable will be fred.

Sorry for the late reply.

In Rust, lifetime annotations are checked at compile-time, not in run-time. But according to the annotation checks, it tweaks things while compiling for run-time. So, it can guarantee the memory safety at run-time.

Hope these answers were helped to remove your confusions. However, use Rust's sub Reddit or official communication channels for a quick response next time :)
