# Entities

Generic system of entities written in zig. Without ABA problems, using

generational index in order to access the associated data. The code is clear and simple to understand.

## Examples

```zig

usingnamespace @import("entities");

pub fn main () void {

  var entities = Entities(f32).init(default_allocator);

  const handle_1 = try entities.append(1.5);

  const handle_2 = try entities.append(2.5);

  const handle_3 = try entities.append(3.5);

  // You could hardcode specific handle id.

  const handle_4 = try entities.append_hard(4.5, 55);

  // Getting the inner data by using associated handle.

  print("{}\n", .{entities.get(handle_2)});

  // Removes data using bucket pooling.

  entities.remove(handle_1);

  // Iterator over all active handles.

  var it = entities.interate();

  while(it.next()) |datum| {

    print("datum: {}\n", .{datum.*});

  }

}

```
