randomstructlayout

This crate provides custom attributes to randomize struct layout, like gcc's Randomizing structure layout(https://lwn.net/Articles/722293/).

Example

```rust use randomstructlayout::layout_randomize; use offset;

[layout_randomize(Debug)]

struct Data { a: i32, b: i32, c: i32, d: i64, e: i64, }

fn main() { let data = Data { a: 0x10, b: 0x20, c: 0x30, d: 0x30, e: 0x40, };

println!("{}", offset::offset_of!(Data::a));
println!("{}", offset::offset_of!(Data::b));
println!("{}", offset::offset_of!(Data::c));
println!("{}", offset::offset_of!(Data::d));
println!("{}", offset::offset_of!(Data::e));

/* example output
20
16
0
8
24
*/

println!("{:x?}", data); // Debug print order is same as normal one.
// Data { a: 10, b: 20, c: 30, d: 30, e: 40 }

} ```
