@ -104,9 +104,11 @@ The most common case is a reference to **static data**, such as string literals:
let s: &'static str = "Hello world!";
```
Since string literals are known at compile-time, Rust's stores them in a memory
region known as ***. *** is part of the executable itself: there is no risk of it
being freed during program execution.
Since string literals are known at compile-time, Rust stores them *inside* your executable,
in a region known as **read-only data segment**.
All references pointing to that region will therefore be valid for as long as
the program runs; they satisfy the `'static` contract.
