Static lifetime
- [Instructor] There is a lifetime name that's reserved in Rust for special purposes, and that is static. The static lifetime indicates that data is available for the entire duration of a program. That data never gets dropped, so you can safely reference it at any time. For example, the text for a string literal is stored directly in the program's binary, so it never goes away. That data is available from start to finish. Therefore, all string literals have a static lifetime, which can be annotated as shown here. The static lifetime can be associated with a reference to indicate that it will never become invalid and that it lives longer than any other lifetime. However, references that have a static lifetime such as string literals can be coerced to other more restrictive lifetimes if that reference is passed as the output parameter from a function with another lifetime annotation, though that's rarely done.
