Static safina_db::STORE_MUTEX

source · 
pub static STORE_MUTEX: Lazy<Mutex<Store>>
Expand description

A globally accessible, thread-safe, lazily initialized instance of Store.

§Details

  • static STORE: Declares a static variable named STORE that is globally accessible.
  • Lazy<Mutex<Store>>: Uses the Lazy type from the once_cell crate to defer the initialization of the Store instance until it is first accessed. The Mutex ensures that access to the Store is thread-safe by allowing only one thread to access it at a time.
  • Lazy::new(|| Mutex::new(Store::new())): This line initializes the STORE variable using a closure (|| syntax). The closure creates a new Mutex which wraps a new instance of Store. The Lazy::new function ensures that this initialization happens only once, no matter how many times STORE is accessed.

§Example

// Accessing the global STORE instance
let mut store = safina_db::STORE_MUTEX.lock().unwrap();
store.insert("key", "value");
