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();
hs.insert("foo");
hs.insert("bar");
assert!(hs.contains("foo"));
Output example
assertion successful
Code explanation
use std::collections::HashSet;
: imports the HashSet type from the standard librarylet mut hs = HashSet::new();
: creates a new, empty HashSeths.insert("foo");
: inserts the string "foo" into the HashSeths.insert("bar");
: inserts the string "bar" into the HashSetassert!(hs.contains("foo"));
: checks if the HashSet contains the string "foo"
