Module schema 

Shared schema for the .dmap archive file format.

Layout on disk (all little-endian):

+---------------------------------------+
| FileHeader (fixed, 32 bytes)          |
+---------------------------------------+
| rkyv-archived Dictionary              |
|   .index  : Vec<IndexEntry>  sorted   |
|   .records: Vec<TagRecord>            |
|   .strings: Vec<u8> pool              |
+---------------------------------------+

The index is sorted by (group, element, creator_hash) so lookup is a plain binary search. String fields inside TagRecord are stored as (offset, len) into strings; the reader slices without copying.

Structs

ArchivedDictionary

An archived Dictionary

ArchivedIndexEntry

An archived IndexEntry

ArchivedTagRecord

An archived TagRecord

Dictionary

Root archived object in the .dmap file body.

DictionaryResolver

The resolver for an archived Dictionary

FileHeader

32-byte file prefix. Kept outside rkyv so we can sanity-check before attempting to deserialize the body.

IndexEntry

One entry in the sorted lookup index.

IndexEntryResolver

The resolver for an archived IndexEntry

TagRecord

One fully resolved tag record.

TagRecordResolver

The resolver for an archived TagRecord

Enums

ArchivedVrCode

An archived VrCode

VrCode

DICOM value representation, 2-byte ASCII packed into one byte via a fixed enum so records stay small.

VrCodeResolver

The resolver for an archived VrCode

Constants

MAGIC

VERSION

Functions

canonicalize_creator

Canonicalize a private creator string the same way the Python normalize stage does: uppercase, collapse internal whitespace.

creator_hash

Compute the index key hash for a creator (0 for public tags).

fnv1a32

FNV-1a 32-bit. Used for creator-hash in the index key.
