@sparknack 🔍 Important: PR Classification Needed!

For efficient project management and a seamless review process, it's essential to classify your PR correctly. Here's how:

1. If you're fixing a bug, label it as kind/bug.
2. For small tweaks (less than 20 lines without altering any functionality), please use kind/improvement.
3. Significant changes that don't modify existing functionalities should be tagged as kind/enhancement.
4. Adjusting APIs or changing functionality? Go with kind/feature.

For any PR outside the kind/improvement category, ensure you link to the associated issue using the format: “issue: #”.

Thanks for your efforts and contribution to the community!.

recommend to use enum class

added.

[foxspy]

A size field should be reserved, and the size should be written first, and then the data; deserialization corresponds to it; it is easy to make mistakes if you rely on the size of the input string

code has been removed since we want to redesign the file header later.
