Nested bind_executor fails to build #1428

Open anarthal opened 4 months ago

anarthal commented 4 months ago

This limits the use of bind_executor in generic code.

#include <boost/asio/bind_executor.hpp>
#include <boost/asio/system_executor.hpp>
#include <boost/asio/io_context.hpp>

namespace asio = boost::asio;

int main() {
    asio::io_context ctx;

    auto tok = asio::bind_executor(
        asio::system_executor(),
        asio::bind_executor(
            ctx.get_executor(),
            []{}
        )
    );
}
