Senders and Receivers for the GNOME Glib library 

===============================================

This is a small C++ library that glues together the Glib event loop and the current executor proposal for C++.

It can be used to compose asynchronous tasks in a Glib event loop.

Since single-valued senders can be automatically converted to awaitable objects, the library also provides a way to use C++ coroutines in a Glib event loop.

The library requires C++20.

Example

```cpp

#include "glib-senders/glib_io_context.hpp"

#include "glib-senders/file_descriptor.hpp"

#include 

using namespace gsenders;

exec::task write(file_descriptor fd, std::span buffer) {

  while (!buffer.empty()) {

    buffer = co_await async_write_some(fd, buffer);

  }

} 

exec::task echo(file_descriptor in, file_descriptor out) {

  char buffer[1024];

  int n = 0;

  for (int n = 0; n < 10; ++n) {

    std::span received = co_await async_read_some(in, buffer);

    co_await write(out, received);

  }

} 

int main() {

  glib_io_context ctx{};

  file_descriptor in{STDIN_FILENO};

  file_descriptor out{STDOUT_FILENO};

  stdexec::start_detached(echo(in, out) | stdexec::then([&] { ctx.stop(); }));

  ctx.run();

}

```
