Deserialising binary data in Rust

(Posted 2024-08-14 17:11:15)

One common way to deal with serialised data in C++ is to map to a struct, but in Rust with memory ownership and some smart memory optimizations, it is a little more complicated.

For example, let's say a producer in C++ serialises this message:

struct book_msg {  
    uint8_t major_version, // byte 0: message major version  
    uint8_t minor_version, // byte 1: message minor version  
    uint8_t msg_type,      // byte 2: message type  
    uint8_t title[20]      // byte 3-23: title of the book  
}
// ....
auto msg = create_msg();
comm.send(&msg, sizeof(book_msg));

How can we deserialise that in Rust?

How to use Flatbuffers in a C++ project with Conan?

(Posted 2024-02-01 20:04:40)

In a C++ project I am currently working, we are using CMake/Conan for dependency resolution and planning to use flatbuffer to serialise some messages. When searching for documentation, I noticed that flatbuffers documentation is not the best one and that the integration with CMake is even harder to find, therefore, I decided to write a recipe on how to integrate it to reduce the misery of other developers around.

First, let me explain quickly how it works.

Having fun in life!

I was talking to a friend about cellular automata using Conway's Game of life as an example. Curious again after so many years that I've read it, I read again carefully the wikipedia page and I found it fascinating.

What is the better way to learn more? Implementing! However I do not want to implement it in a boring way. I want to have interesting features. Let's first talk a little bit about this 0-player fascinating game.
