HashMap in Hoshi-lang

The hashMap standard library module provides a HashMap<K, V> struct for working with hash maps.

<tt>HashMap<K, V></tt> Struct

The HashMap<K, V> struct is a generic hash map implementation. The key type K must implement the Hashable interface.

Methods

• constructor(): Creates a new, empty HashMap.
• static operator[](this: HashMap<K, V>, key: K) : V: Returns the value associated with the given key. Returns null if the key is not found.
• static operator[](value: V, this: HashMap<K, V>, key: K) : none: Inserts or updates a key-value pair.
• size() : int: Returns the number of key-value pairs in the hash map.
• clear() : none: Removes all key-value pairs from the hash map.
• keys() : K[]: Returns an array of all the keys in the hash map.
• values() : V[]: Returns an array of all the values in the hash map.
• contains(key: K) : bool: Returns true if the hash map contains the given key.
• remove(key: K) : none: Removes a key-value pair from the hash map.

Example

use hashMap "hashMap"
use str "str"
 
func main() : int {
    let map = hashMap.HashMap<str.Str, int>()
    map["Hello"] = 1
    map["World"] = 2
    return 0
}
