Struct ManifestHeader 

pub struct ManifestHeader {
    pub drop_store_version: u16,
    pub metadata_version: u16,
    pub manifest_version: u16,
}

Parsed 16-byte manifest header.

Field widths are fixed: magic (4) + three u16 LE versions (6) + reserved (6). Reserved MUST be zero. The reserved width reconciles the spec’s “first 16 bytes” framing with the field table (which otherwise sums to 14) — see bit-level/35-manifest-header.md and limnifs/spec#13.

Fields

drop_store_version: u16

metadata_version: u16

manifest_version: u16

Implementations

impl ManifestHeader

pub const CURRENT_DROP_STORE_VERSION: u16 = 1

The currently implemented version of each layer. A header that names a future version is parseable structurally but flagged by higher layers (feature-flag policy, spec §18).

pub const CURRENT_METADATA_VERSION: u16 = 1

pub const CURRENT_MANIFEST_VERSION: u16 = 1

pub const fn new( drop_store_version: u16, metadata_version: u16, manifest_version: u16, ) -> Self

pub fn current() -> Self

pub fn to_bytes(self) -> [u8; 16]

Serialise to the 16-byte wire form. Inverse of parse_manifest_header.
