0.2.0 - Breaking changes

• Symble is now renamed to Symbol.
• Symbol field is now serialized as the big endian representation of u8.
• Map EXCHANGE and INFOTYPE are replaced to the enumeration Exchange and InfoType.
  • Use strum to provide the map-like function.
• Some methods in data::hex are removed.
  • Replace your current code to the native method (.to_be_bytes())
  • (beta 5) For UNIX timestamp, use unix_ms_to_six_byte_hex and six_byte_hex_to_unix_ms instead.
• Removed and added some new unused error variants.

0.2.0 - Features

• data::orderbook, data::trade: Use BufReader instead of our based-on-Atomic seek reader.
• data::orderbook, data::trade: Use data::fields to serialize & deserialize.
• Separate the serialization & deserialization of fields to data::fields
• Replace the usize converter of hex::encode_num_to_bytes to a robust implementation
  • Related: Some methods in data::hex are removed.
• data::types: Add Exchange and InfoType while removing EXCHANGE and INFOTYPE.
• data::orderbook: Improve the logic of generate_diff.
• data::hex: Deprecate old inextensible methods (encode_num_to_bytes & decode_num_to_bytes)
  • use u32::encode_bytes and u32::decode_bytes for 5-byte encoding & decoding
• data::hex: Add the u64 to 10-byte encode & decode support
  • use u64::encode_bytes and u64::decode_bytes for 10-byte encoding & decoding
• data::types: Add more exchanges, and add PERIOD.
• Add the encoder and decoder of bbo and kline.
• file::writer: Add tracing log.
• file::writer: Refactored for extensibility.
• Change to wmjtyd's crypto-crawler and crypto-msg-parser.
• (beta 5) Add methods to serialize and deserialize UNIX timestamp to 6-byte u64.

0.2.0 - CI

• Also test if cargo doc can generate correct documentation.
• Run cargo clippy and cargo fmt --check

0.2.0 - Examples

• Add a production example of file::writer.
• (beta 4) data::hex add the testcase of i8 → u8 and u8 → i8

0.2.0 - Bug fixes

• file::writer: Don't create the directory if it has been existed.
• file::writer: .stop() can't work properly.
• (beta 4) {InfoTypeExpr,ExchangeTypeRepr}::try_from_str should be from lowercase
  • Added the test case of this.
• (beta 5) UNIX timestamp should serialize and deserialize to 6-byte u64.
