Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Constructs a connection object from an executor and an optional set of parameters.

any_connection(
    boost::asio::any_io_executor ex,
    any_connection_params params = {});

The resulting connection has this->get_executor() == ex. Any internally required I/O objects will be constructed using this executor.

You can configure extra parameters, like the SSL context and buffer sizes, by passing an any_connection_params object to this constructor.
