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 HashMapmap.insert("key", "value");
: inserts a key-value pair into the HashMaplet borrowed_map = map.borrow();
: borrows the HashMap and stores it in theborrowed_map
variable
