Crate map_to_const

  

Easily convert HashMap<K, V> to constant [(K, V); N] values.

Usage

use map_to_const::*;
use std::collections::HashMap;

fn main() {
    // Create a HashMap in some manner. Ideally, this will be formatted
    // and returned in an API response or similar.
    let my_map = HashMap::from([("testing", "123"), ("hello", "world")]);

    let const_value = map_to_const(&my_map, None);

    println!("{const_value}");

    // later in code, construct the hashmap from the `const` slice:
    // let my_map = HashMap::from(MY_MAP);
}
