serde2file
serialize some data to a file or deserialize a data from a file by
support encrypt/decrypt file
将struct序列化化存储为文件，或者从文件反序列化为struct
文件存储时支持加密存储
derive macro FileSerializeAndDeserialize Attributes（Optional）:
- fileencrypt
- encrypt Data encryption method
- decrypt Data decryption method
- The above encryption and decryption methods must be set at the same time, otherwise encryption and decryption will not be performed.
- #[file
encrypt(encrypt="TestEncryptTool::encrypt",decrypt="TestEncryptTool::decrypt")]
dumpfilename
- Custom dump file name
- If not set ,the default dump file name is the full name of the current Struct.
- For example, the default dump file name corresponding to serde2file::test::TestData is serde2file-test-TestData
- #[dumpfilename = "test_data"]
派生宏FileSerializeAndDeserialize属性(可选)
- fileencrypt
- encrypt 数据加密方法
- decrypt 数据解密方法
- 以上加密和解密方法必须同时设置，否则不进行加解密。
- #[file
encrypt(encrypt="TestEncryptTool::encrypt",decrypt="TestEncryptTool::decrypt")]
dumpfilename
- 设置自定义的转储文件名称
- 自定义转储文件名称
- 默认为当前Struct的完整名称，
- 如serde2file::test::TestData对应的缺省转储文件名称为serde2file-test-TestData
- #[dumpfilename = "test_data"]
