rustHow to create a thread safe hashmap in Rust?

Creating a thread safe hashmap in Rust is possible using the HashMap type from the std::collections module.

use std::collections::HashMap;
use std::sync::{Arc, Mutex};

let hashmap: Arc<Mutex<HashMap<String, String>>> = Arc::new(Mutex::new(HashMap::new()));

The example code above creates a thread safe HashMap using the Arc and Mutex types. Arc is used to share the HashMap between threads, and Mutex is used to ensure that only one thread can access the HashMap at a time.

• Arc: A type used to share data between threads.
• Mutex: A type used to ensure that only one thread can access a piece of data at a time.
• HashMap: A type used to store key-value pairs.
