How does one find the size of a deku binary representation (for fixed size)

[amaank404]

#[derive(DekuRead, DekuWrite, Debug, PartialEq)]
#[deku(endian = "big")]
struct AifsLayer1Header {
    magic: u32,
    size: u64,
    level: u8,
    reserved: [u8; 1000],
}

suppose this is the struct

how do i get the size of the struct's binary representation in number of bytes.

For that struct, since you don't have deku attributes on the fields and everything's standard, you can use mem::size_of.

If you start using deku attributes on the fields, there is an open issue for that feature: #307

ty!! but won't the alignment of struct cause issues?
