# buf_sized
Calculate accumulated buffer sizes of types.
Unlike `std::mem::size_of<T>()`, this crate calculates the size of the buffer that would be required to serialize the
type without taking alignment into account.
## Usage
```rust
use buf_sized::buf_size;
use buf_sized_derive::BufSized;
#[derive(BufSized)]
struct Data {
header: u8,
num: u128,
payload: [u8; 12],
crc: u32,
}
#[test]
fn test_struct() {
assert_eq!(buf_size::<Data>(), 1 + 16 + 12 + 4);
}
```
