# Lazy-RE

A simple proc macro for the lazy reverse engineers.

It basically creates the padding for you.

```rust

#[repr(C, packed)]

#[lazy_re]

struct Lights {

    #[lazy_re(offset = 0x10)]

    x: f32,

    y: f32,

    z: f32

}

#[repr(C, packed)]

#[lazy_re]

struct PlayerEntity {

    #[lazy_re(offset = 0x48)]

    light: Lights,

    #[lazy_re(offset = 0x90)]

    player_x: f32,

    player_y: f32,

    player_z: f32,

}

```

That would create the padding for the `Light` struct at the beginning, i.e.

the `x` field will be at the offset `0x10`, and the rest is filled with `[u8;

0x10]`.

Similarly, the PlayerEntity will have padding until the `Light` struct, and

then it'll pad between the light and the player position, doing the math for

you.
