This crate offers declarative macros for initializing collections from the 

[standard library][std] and [hashbrown][hashbrown].

This crate has zero dependencies and is `#![no_std]` if you opt-out of

support for the standard library collections.

## Example

```rust

use map_macro::hash_map;

let hello = hash_map! {

    "en" => "Hello",

    "de" => "Hallo",

    "fr" => "Bonjour",

    "es" => "Hola",

    "cat" => "Hola",

    "🌍" => "👋",

};

```
