mapro

A tiny macro library for creating std::collections.

Overview

mapro provides a set of convenient macros for creating various standard library collections, such as HashMap, BTreeMap, HashSet, BTreeSet, VecDeque, and BinaryHeap.

The name mapro is a portmanteau of "macro" and "map", but the library handles more than just map types.

Usage

To use mapro, add it to your Cargo.toml dependencies:

[dependencies]
mapro = "0.1.0"

or run:

cargo add mapro

Then import the macros you want to use in your Rust files:

use mapro::{map, bt_map, set, bt_set, vec_d, heap};

Examples

Creating a HashMap:

let m = map!{
    "one" => 1,
    "two" => 2
};

assert_eq!(m["one"], 1);
assert_eq!(m["two"], 2);

Creating a HashSet:

let s = set!{1, 2, 3};

assert!(s.contains(&1));
assert!(s.contains(&2));
assert!(s.contains(&3));

Features

  • Simple API: Using mapro is as straightforward as using any Rust macro.

  • No Extra Dependencies: mapro only depends on the standard library.

  • Broad Collection Support: Supports various standard library collections out of the box.
