#使用Rust实现FlatBuffers
需要手动遍历序列化的实例的每个字段，但是序列化需要更大空间
类型暂时仅支持 String， bool， Vec， Struct， 可以相互嵌套
直接定位解析数据位置，速度更快
#Structure
- flatbuffer - Define the structure of the FlatBuffers.
- flatbuffer_var - Define some types in FlatBuffers.
- flatbuffer_helper - Realize the transform between primitive type and FlatBufferVar
- flatbuffer_builder - Create a FlatBuffer instance, add fields to FlatBuffer
- flatbuffer_handler - Get the filed which you want in bytes
- flatbuffer_manager - Save primitive struct infomation
#Future to do
Convert primitive type to Vec faster ? Add more primitive type
#Issue
How to make Type V convert to Vec if V is Vec<_> ?
