println!("{}", std::mem::size_of::<*mut i32>());
println!("{}", std::mem::size_of::<*mut [u8]>());
I thought the print results should be the same, after all, pointers are essentially memory addresses. And the size of memory addresses should be the same.
However, when I run the above code, it turns out the size of i32 pointer is 8 while the size of array pointer is 16. How is that coming? Maybe some inner mechanism of array is affecting the result, could somebody explain this to me? Thanks.
