rustHow to create a HashSet from a Vec in Rust?
Creating a HashSet from a Vec in Rust is easy and can be done with the collect method.
let vec = vec![1, 2, 3];
let set: HashSet<i32> = vec.into_iter().collect();The output of the above code will be a HashSet containing the elements of the Vec:
{1, 2, 3}The code works by taking the elements of the Vec and collecting them into a HashSet. The collect method takes an iterator and collects its elements into a collection.
