Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Struggle with C++ 20 Coroutines
PS: Take a look at cppcoro; this might help as well, especially generator<>, if you're looking to generate numbers, and stuff;
-
Does C++23 have a coroutine task promise type?
This is the only viable implementation.
-
Stop Comparing Rust to Old C++
Kind of sounds like whatever library you were using provided leaky abstractions. Something like cppcoro provides really good abstractions for coroutines, the user really doesn't need to understand why any of it works.
-
Sane coroutine imitation with macros; copyable, serializable, and with reflection
Is there a usecase for copying/serializing such coroutines? If not, I would use the normal C++20 coroutines (cppcoro?).
-
Is Tokio::sync::Mutex lock-free?
C++ has the popular CppCoro library. Async_mutex is its equivalent of Tokio::sync::Mutex, providing exclusive access to data shared between tasks.

My thoughts and dreams about a standard user-space I/O scheduler
Because the whole application is running under a single thread there is no need for atomic operations in synchronization primitives(which most of the time requires seq_cst memory order and CMPXCHG which is an expensive instruction in CPU). for example what async_mutex would look like if it knows it's running in a single-threaded scheduler (a non-atomic state variable and waiters queue).
-
[Discussion] What are some old C++ open source projects you wish were still active?
Maybe not old, but I wish cppcoro was still updated. It was such a nice start!

A high-level coroutine explanation
You can get generator<> from https://github.com/lewissbaker/cppcoro

C++ Coroutines Do Not Spark Joy
It is possible to compose them more easily than described in the article; Lewis Baker's cppcoro library for example provides a recursive_generator<> type[0] that allows this without using any macros. It's up to the library part of coroutines to make things easy, end users are not expected to write low-level coroutine code themselves.
I wonder about the allocation elision. Return value optimization became mandatory, and some compilers can already elide calls to new/delete and malloc()/free() in normal code, so perhaps it will be possible to guarantee allocation elision in the future in the most used cases.

Download from Google drive
It appears that Google wrote some utilities to do this without manually having to deal with HTTP, but they are only available in Java, Python, Node.js, PHP and .NET - not C++. So you will have to write your own C++ library that sends HTTP requests to the web API and handles the received messages and data. You will need some library to handle network sockets and HTTP requests, such as libcurl or Boost Beast (or see under Communication here: https://en.cppreference.com/w/cpp/links/libs)

My thoughts and dreams about a standard user-space I/O scheduler
For example Boost-Beast and Boost-Mysql(not officially boost) receive user provided asio::io_context and every other library in this ecosystem should be the same.
