Data Structure Alignment

Size of struct will differ based on compiler.

This struct in C will be 16 bytes

typedef struct {
  int a;
  double b;
} Point;

This struct will be 12 bytes

#[derive(Serialize, Deserialize, Debug)]
struct Point{
    x: i32,
    y: f64,
}

Therefore a raw serialized data may not always be deserializable in a different compiler
