How to use the lazy initialization pattern with Rust 1.80

Lazy initialization can improve the performance of Rust applications by delaying the resource initialization until actually needed. Previously, crates like `lazy_static` and `once_cell` were used for this pattern. With Rust 1.80, the standard library now supports lazy initialization through types like `OnceLock` and `LazyLock`, reducing the need for external dependencies. These native types offer advantages such as fewer dependencies and direct maintenance by the Rust standard library team.
