Trait lv2rs_atom::array::ArrayAtomHeader

pub trait ArrayAtomHeader: Sized {
type InitializationParameter: ?Sized;
    unsafe fn initialize<'a, W, T>(
        writer: &mut W, 
        parameter: &Self::InitializationParameter, 
        urids: &mut CachedMap

}

A header of an ArrayAtomBody.

Many atoms have an additional body header and this trait represents said headers.
