rustHashshet example in Rust

Hashset is a data structure in Rust that stores unique values. It is implemented using a hash table, which allows for fast lookups and insertion of elements.

Example code

use std::collections::HashSet;

let mut hs = HashSet::new();



Output example

assertion successful

Code explanation

  • use std::collections::HashSet;: imports the HashSet type from the standard library
  • let mut hs = HashSet::new();: creates a new, empty HashSet
  • hs.insert("foo");: inserts the string "foo" into the HashSet
  • hs.insert("bar");: inserts the string "bar" into the HashSet
  • assert!(hs.contains("foo"));: checks if the HashSet contains the string "foo"
