rustHow to borrow hashmap in Rust


HashMap is a data structure in Rust that allows you to store key-value pairs. To borrow a HashMap, you can use the borrow() method. This will return a Ref<HashMap> which is a reference to the HashMap.

Example:

let mut map = HashMap::new();
map.insert("key", "value");

let borrowed_map = map.borrow();

The borrow() method returns a Ref<HashMap> which is a reference to the HashMap. This reference can be used to access the data stored in the HashMap.

Code explanation

  • let mut map = HashMap::new();: creates a new HashMap
  • map.insert("key", "value");: inserts a key-value pair into the HashMap
  • let borrowed_map = map.borrow();: borrows the HashMap and stores it in the borrowed_map variable
