I'm new to HLSL programming and I want to use a struct variable to init another one, i.e. to use a "copy constructor" in C++.

Since struct is customized data structure, I wonder if we can use a "=" to do the copy initialization?

e.g.

struct MyStruct {
	int a;
	float4 n;
}

MyStruct s1;
s1.a = 1;
s1.b = float4(1.f);

MyStruct s2 = s1;

Is the above code usable?

Yes
