tec::NdTypes::ElemHeader Struct Reference

Per-element header describing the following data item. More...

#include <tec_nd_types.hpp>

Public Member Functions
	ElemHeader ()
	Default constructor (unknown element).
	ElemHeader (Tag _tag, Size _size, Count _count=1)
	Construct with explicit tag, size, and count.

Public Attributes
Tag	tag
	Type and property tag.
Size	size
	Payload size in bytes (excluding this header).
Count	count
	Number of elements (for containers/sequences; 1 for scalars).

Detailed Description

Per-element header describing the following data item.

Fixed size: 8 bytes. Precedes every serialized element.

Byte layout

Byte	Size	Field	Type	Description
0–1	2	tag	Tag (uint16_t)	Type and property tag (encodes scalar/float/signed/sequence/container/object etc.).
2–5	4	size	Size (uint32_t)	Payload size in bytes excluding this ElemHeader (0 for containers/objects that compute size dynamically).
6–7	2	count	Count (uint16_t)	Number of elements: - 1 for scalars and sequences - Actual count for containers (clamped to 65535)

This layout is guaranteed to be contiguous and exactly the sizes shown on all platforms due to the packing directive.
