• Primitive types: i8, i16, i32, i64, u8, u16, u32, u64, f32, f64, bool
• String type: variable-length UTF-8 string
• Vec: variable-length byte array

Panics

Panics if struct contains unsupported field types or unnamed fields

Example:

use hdds_codegen::DDS;

#[derive(DDS)]
struct ImageMeta {
    image_id: u32,
    width: u16,
    height: u16,
    format: String,      // Variable-length string
    data: Vec<u8>,       // Variable-length byte array
}
