zxc_block_header_t Struct Reference

On-disk header structure for a ZXC block (8 bytes, little-endian). More...

#include <zxc_internal.h>

Data Fields
uint8_t	block_type
	Block type (see zxc_block_type_t).
uint8_t	block_flags
	Flags (e.g., checksum presence).
uint8_t	reserved
	Reserved for future protocol extensions.
uint8_t	header_checksum
	Header integrity checksum (1 byte).
uint32_t	comp_size
	Compressed size excluding this header.

Detailed Description

On-disk header structure for a ZXC block (8 bytes, little-endian).

raw_size is not stored in the header; decoders derive it from Section Descriptors within the compressed payload.
