I have got a plenty of structs in my project. Their size varies

Is there a rule of thumb that states which structs I pass by

Thanks.

My wish:
New `std.io` package that includes `std.file`, `std.path` and
`std.stdio` modules.
I want to create a static array large enough to store 1MB of
float values.
What am I doing wrong?
Here is a sample code with notes:
void main(string[] args) {
enum size_t COUNT = 1024 * 512 / float.sizeof; // works OK :)
//enum size_t COUNT = 1024 * 512 * 2 / float.sizeof; //
Which type it better to use for array's indices?
float[] arr = new float[10];
int i;
long j;
size_t k;
// which one is better arr[i], a[j]or arr[k] ?
It seem like `size_t` suites well because 'is large enough to
represent an offset into all addressible memory.'
