map-to-const

github crates.io docs.rs build status

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

This crate works with Cargo with a Cargo.toml like:

toml [dependencies] map-to-const = "0.1.0"

Getting started

Add some usage to your application.

Here's an example of using map-to-const in code:

```rust use maptoconst::*; 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([("hello", "world"), ("testing", "123")]);

let const_value = map_to_const(&my_map, "my const name");

println!("{const_value}");
// prints:
//   const MY_CONST_NAME: [(&str, &str); 2] = [
//       ("hello", "world"),
//       ("testing", "123"),
//   ];

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

} ```
