# drift macros

misc helpful macros 

## #[assert_no_slop]

throws compile-time error if repr(C) struct has hidden padding (slop)

```rust

#[assert_no_slop]

#[account(zero_copy)]

#[repr(C)]

pub struct Foo {

    pub bar: u128,

    pub baz: u8,

    pub qux: u128,

}

```

this will throw a compile-time error because `Foo` has 7 bytes of hidden padding between `baz` and `qux`
