Struct ObjectHeaderMessage 

pub struct ObjectHeaderMessage {
    pub msg_type: u8,
    pub flags: u8,
    pub creation_index: u16,
    pub data: Vec<u8>,
}

A single message within an object header.

Fields

msg_type: u8

Message type ID (e.g., 0x01 = Dataspace, 0x03 = Datatype, etc.)

flags: u8

Per-message flags (bit 0 = constant, bit 1 = shared, etc.)

creation_index: u16

Creation index, written only when the header tracks attribute creation order (flags bit 2). Only the attribute message class has one in libhdf5 — H5O_msg_class_t::get_crt_index is null for every other type, leaving the field zero (H5O_msg_append_real).

data: Vec<u8>

Raw message payload.
