Struct PackHeader 

pub struct PackHeader {
    pub format_version: u32,
    pub asset_count: u32,
    pub flags: u32,
}

Decoded form of the 24-byte header at the start of data.pack.

Byte layout (all little-endian):

offset  size  field
──────  ────  ─────────────────────────────────────────────────────
     0     8  PACK_MAGIC (b"KHORAPK\0")
     8     4  format_version: u32  — must equal PACK_FORMAT_VERSION
    12     4  asset_count:    u32  — sanity check vs. index.bin
    16     4  flags:          u32  — bit 0 LZ4, bit 1 manifest
    20     4  reserved:       u32  — zero on writes, ignored on reads

Fields

format_version: u32

Format version as written. Equals PACK_FORMAT_VERSION on a pack produced by this engine; loader refuses anything else.

asset_count: u32

Number of assets the producer claims to have written into this data.pack. Cross-checked against index.bin.len() at boot to catch a mismatched pair (e.g. user shipped only one of the two files).

flags: u32

Pack-level feature flags (compression, manifest, …). See PACK_FLAG_* constants.

Implementations

impl PackHeader

pub fn to_bytes(&self) -> [u8; 24]

Encodes the header into 24 raw bytes ready to be prepended to data.pack. Used by PackBuilder.

pub fn v2(asset_count: u32, flags: u32) -> Self

Convenience for the writer: build the v2 header for a pack that will contain asset_count blobs and optional feature flags.
