WDB2 header (Cataclysm 4.0+)

The WDB2 format was introduced in Cataclysm and has two variants:

• Basic header (build <= 12880): 28 bytes
• Extended header (build > 12880): 48 bytes + optional index arrays

Reference: https://wowdev.wiki/DB2 Reference: TrinityCore DB2StorageLoader.cpp

Fields

magic: [u8; 4]

The magic signature, should be “WDB2”

record_count: u32

Number of records in the file

field_count: u32

Number of fields in each record

record_size: u32

Size of each record in bytes

string_block_size: u32

Size of the string block in bytes

table_hash: u32

Table hash

build: u32

Build number

timestamp: u32

Timestamp (only present in extended header)

min_index: i32

Minimum ID in the file

max_index: i32

Maximum ID in the file

locale: i32

Locale flags

copy_table_size: u32

Copy table size (unused in Cataclysm, always 0)

has_extended_header: bool

Whether this header uses the extended format

index_array_size: u64

Size of the index array section (to be skipped)

Implementations

impl Wdb2Header

pub const BASIC_SIZE: usize = 28

The size of a basic WDB2 header in bytes (build <= 12880)

pub const EXTENDED_SIZE: usize = 48

The size of an extended WDB2 header in bytes (build > 12880)

pub const EXTENDED_BUILD_THRESHOLD: u32 = 12880

Build number threshold for extended header format

pub fn parse<R: Read + Seek>(reader: &mut R) -> Result<Self>

Parse a WDB2 header from a reader

This handles both the basic (build <= 12880) and extended (build > 12880) formats. For builds > 12880, also skips the index arrays if max_index != 0.

pub fn to_dbc_header(&self) -> DbcHeader

Convert to a standard DBC header

pub fn header_size(&self) -> u64

Calculates the size of the header including any index arrays

pub fn record_data_offset(&self) -> u64

Calculates the offset to the record data

pub fn string_block_offset(&self) -> u64

Calculates the offset to the string block

pub fn total_size(&self) -> u64

Calculates the total size of the WDB2 file

Trait Implementations

impl Clone for Wdb2Header

fn clone(&self) -> Wdb2Header

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Wdb2Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Wdb2Header

fn eq(&self, other: &Wdb2Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
