Rust Hashset

Comment

use std::collections::HashSet;
// Type inference lets us omit an explicit type signature (which
// would be `HashSet<String>` in this example).
let mut books = HashSet::new();

// Add some books.
books.insert("A Dance With Dragons".to_string());
books.insert("To Kill a Mockingbird".to_string());
books.insert("The Odyssey".to_string());
books.insert("The Great Gatsby".to_string());

// Check for a specific one.
if !books.contains("The Winds of Winter") {
    println!("We have {} books, but The Winds of Winter ain't one.",
             books.len());
}

// Remove a book.
books.remove("The Odyssey");

// Iterate over everything.
for book in &books {
    println!("{book}");
}

use hashset::hashset;
//	The `hashset!` macro is provided by this crate.

fn main() {
    let mut set = hashset!["a", "b", "c"];
    set.insert("d");
    set.remove("a");
    assert!(set.contains("d"));
    for x in &set {
        println!("{}", x);
    }
