Crate dataparser_core 

dataparser – A configurable binary serialization and deserialization framework

dataparser provides a flexible and extensible framework for working with structured binary formats. It supports both serialization and deserialization, including streaming decoding, custom encoding logic, endianness control, optional encryption, and macro-derived implementations for serializing structs.

Features

• Custom binary format parsing and writing
• Configurable options (strict_encoding, trim_nulls, endianness, etc.)
• Optional length-prefixed fields
• Zero-copy or stream-based decoding
• AES-256-CBC encryption (behind the crypto feature)
• #[derive(StructSerialize, StructDeserialize)] support (behind the derive feature)

Example: Encode and Decode a Struct

use libparser::{DataEncoder, DataParser, Encodable, Decodable, ParseResult};

#[derive(Debug)]
struct Header {
    id: u32,
    flag: bool,
}

impl Encodable for Header {
    fn encode_data(&self, encoder: &mut DataEncoder) -> ParseResult<()> {
        encoder.add_u32(self.id)?;
        encoder.add_bool(self.flag)?;
        Ok(())
    }
}

impl Decodable for Header {
    fn decode_data(parser: &mut DataParser) -> ParseResult<Self> {
        let id = parser.get_u32()?;
        let flag = parser.get_bool()?;
        Ok(Header { id, flag })
    }
}

Features

• derive: Enables #[derive(StructSerialize, StructDeserialize)]
• crypto: Enables AES-256 encryption with PKCS7 padding
• async : Enables async stream reader/writer support via the tokio crate

Modules

• encoder: Binary serialization
• parser: Binary deserialization
• options: Runtime configuration for encoding/parsing
• crypto: AES encryption support (optional)
• utils: Shared helpers, endian utilities

Trait Overview

• Encodable — custom serialization
• Decodable — custom deserialization
• StreamDecodable — streaming-compatible deserialization
