A simplified variant of Google's ProtoBuf.

format

A simple-protobuf file can be filled into a C struct directly, but no pointer is supported.

The sp file format is shown below.

[struct_len] + n*[[type][data_len][data]]
  1. type is a length-variable LE number(less than 2^57^) indicating the aligned type length of each struct item.
  2. *_len is a length-variable LE number(less than 2^57^) indicating the length of *.
  3. data contains data_len bytes of the data.

usage

You can read test.c to find out the detailed usage.

Save a struct

1. Create items type length info array

This array has type uint64_t, which indicates the aligned length of each struct item. You should call align_struct to get that array.

2. Call set_pb to save

Read into a struct

1. Open file

2. Call get_pb to read
