# CompMap

Compile time hash map that supports keys and values of different data types

## 📦 Installing

### 1. Download [compmap](https://raw.githubusercontent.com/blockkwork/compmap/main/src/hashmap.zig)

### 2. Copy the code to a zig file (example hmap.zig)

### 3. Add import to your code:

```zig

const hmap = @import("hmap.zig")

```

## 🚀 Usage

```zig

var hmap = try hashmap.HashMap(u64, u64).init();

defer hmap.deinit();

// 123 - key

// 900 - value

hmap.put(123, 900);

hmap.put(321, 100);

hmap.del(123);

std.debug.print("{}", .{hmap.get(321).?}); // output: 100

```

### Compmap with `[]const u8` type

```zig

var hmap = try hashmap.HashMap([]const u8, u32).init();

defer hmap.deinit();

hmap.put("compmap", 900);

hmap.put("hello", 777);

// get value

const result = hmap.get("hello");

std.debug.print("{}\n", .{result.?}); // output: 777

try hmap.clear(.{}); // delete all buckets

```
