Anybuf

Anybuf is a minimal (like seriously), zero dependency protobuf encoder to encode anything. It is designed to create the value bytes of a protobuf Any, hence the name.

Anybuf allows you to do things wrong in many ways and you should have a solid understanding of how protobuf encoding works in general to better understand the API.

Non goals

• Decoding
• protobuf 2 things
• Field sorting

Supported:

• Varint (u64)
• Repeated: Just append a field multiple times
• Nested: Just append an Anybuf instance

Non supported

• Fixed length types

How to use it

```rust use anybuf::Anybuf;

let data = Anybuf::new() .appenduint64(1, 4) // field number 1 gets value 4 .appendstring(2, "hello") // field number 2 gets a string .appendbytes(3, b"hello") // field number 3 gets bytes .appendmessage(4, &Anybuf::new().appendbool(3, true)) // field 4 gets a message .appenduint64(5, 23) // field number 5 is a repeated uint64 .appenduint64(5, 56) .appenduint64(5, 192) .into_vec(); // done

// data is now a serialized protobuf doocument ```
