I'm porting some of my Java Game Engine code to C++, but I don't know what's the equivalent to a Record class (object) from Java. My first thought was making a struct but I don't know how much overhead it will do in my project if used much.

Here's what I want:

public record Color (float r, float g, float b, float a) {}

And what I tried on C++:

#pragma once

namespace core {
    
    struct Color {
    public:
        float r, g, b, a;

        Color(float red, float green, float blue, float alpha = 1.0f)
            : r(red), g(green), b(blue), a(alpha) { }
    };

}
