Crate dvpl_engine 

DVPL file format engine for World of Tanks Blitz.

Provides encode and decode for the DVPL container format used by WoT Blitz game assets. Usable as a pure Rust library (cargo add dvpl-engine) or as a Python extension via PyO3 (pip install dvpl-converter).

DVPL format

A .dvpl file is a payload followed by a 20-byte footer:

Field	Size	Encoding
original_size	4 bytes	little-endian
compressed_size	4 bytes	little-endian
crc32	4 bytes	little-endian
compression	4 bytes	little-endian
magic	4 bytes	b"DVPL"

Compression types: COMP_NONE (0), COMP_LZ4 (1), COMP_LZ4_HC (2).

Examples

use dvpl_engine::COMP_LZ4_HC;
use dvpl_engine::decode;
use dvpl_engine::encode;

let original = b"Hello DVPL!";
let dvpl_blob = encode(original, COMP_LZ4_HC).unwrap();
let decoded = decode(&dvpl_blob).unwrap();
assert_eq!(original.as_slice(), &decoded);

Enums

DvplError

All failure modes during DVPL encode/decode.

Constants

COMP_LZ4

Standard LZ4 block compression.

COMP_LZ4_HC

LZ4 high-compression mode (better ratio, slower compression).

COMP_NONE

No compression - payload stored as-is.

Functions

decode

Decode a DVPL blob: validate footer, verify CRC32, decompress payload.

encode

Encode raw data into a DVPL blob: compress, compute CRC32, append footer.
