The original title is a tutorial/chapter title about Rust memory management. Let me rewrite it for a mobile feed while preserving key facts.
Original: [Advanced Rust] 1.6. Memory Part 4 - Static Memory and the 'static Lifetime Annotation
Short summary
A detailed tutorial covering static memory in Rust and the 'static lifetime annotation. It explains that 'static means a reference is valid for the program's entire duration but doesn't require data to be stored in static memory. The article also distinguishes const from static, noting constants have no runtime storage since they're inlined at compile time.
- •Static memory holds program binary, static variables, and constants for the program's lifetime
- •'static lifetime means a reference is valid for the entire program duration, not that data must be in static memory
- •const values are compile-time inlined with no runtime storage, unlike static variables
