rustHow to convert a slice to a hashset in Rust?

A HashSet is a data structure in Rust that stores unique values. It can be created from a slice using the from_iter method.

use std::collections::HashSet;

let slice = [1, 2, 3, 4];
let set: HashSet<i32> = HashSet::from_iter(slice.iter().cloned());

The code above creates a HashSet from a slice of i32 values. The iter() method is used to iterate over the slice and the cloned() method is used to clone each element of the slice into the HashSet.

• let slice = [1, 2, 3, 4];: creates a slice of i32 values
• let set: HashSet<i32> = HashSet::from_iter(slice.iter().cloned());: creates a HashSet from the slice using the from_iter method
