pfr VS create-rust-app

This single feature opens a world of new possiblities. For example, it makes implementing "getting the number of fields" trivial. Furthrmore, and much more importantly, it enables turning a struct into a tuple. Currently, this can only be done by enumerating cases (therefore it's not fully generic), as with Boost PFR. By the way, PFR greatly simplifies our codebases, especially for parts with serialization and/or reflection.

The code is relatively short and can be groked with a few coffees: https://github.com/boostorg/pfr/tree/develop/include/boost/pfr ; if you're using C++17 it uses a binary search (https://github.com/boostorg/pfr/blob/develop/include/boost/pfr/detail/fields_count.hpp) to count the number of fields in a struct, by starting by the observation that a likely majorant on the number of fields in a struct is sizeof(the struct) * CHAR_BIT, assuming not too many [[no_unique_address]] tomfooleries. Then once this count is known it's possible to simply map them as a tuple through sheer brute force and destructuring: https://github.com/boostorg/pfr/blob/develop/include/boost/pfr/detail/core17_generated.hpp

I wonder if the c++ approach of boost.pfr would be portable to rust ? It allows reflection on aggregates without needing to annotate anything: https://github.com/boostorg/pfr

It is an 'interesting' meta-programming problem though (wasted many weeks on it myself, fixed a small gcc bug - a 'uniform init' edge case and filed an issue with magic_get Reflecting array members of aggregate structs).

So, you're looking for create-rust-app?

It's finally come together! If this peaked your interest, check out https://github.com/Wulf/create-rust-app

hey r/reactjs, just wanted to share some work revolving around integrating dsync with create-rust-app.

hey r/rust! I just finished testing and releasing the `dsync` integration with create-rust-app. Let me know what you think!~

tsync by Wulf created as part of the awesome Create Rust App utility for setting up fullstack Rust apps. It's available on crates.io

Wowowowow thanks for your efforts behind this!

I’ve integrated vite with a rust backend[1] and so many people have asked me how I managed to achieve SSR because they equate SSR with render+hydrate but it’s really just classical SSR. I think I can finally make their dreams come true because of this.

I mainly wrote this as a database-first approach for create-rust-app
