rustHow to lock a Rust HashMap?
A Rust HashMap can be locked using a Mutex or RwLock.
Example code using a Mutex:
use std::collections::HashMap;
use std::sync::Mutex;
let mut map = HashMap::new();
let mutex = Mutex::new(map);The code above creates a HashMap and a Mutex to lock it.
To access the HashMap while it is locked, use the lock method of the Mutex:
let mut guard = mutex.lock().unwrap();
guard.insert(1, "one");The code above acquires a lock on the Mutex and inserts a key-value pair into the HashMap.
