Provide an example on how to use `rustls::server::Acceptor`

Hello,

I am new to both Rust and async in Rust with tokio so there might be something I might have missed or don't know. Rustls recommends here to use rustls::server::Acceptor for retrieving server certificates dynamically based on ClientHello when working in async manner. But I could not find any useful information on how to use that with Tokio-rustls.

What I have observed is Acceptor implements read_tls method which accepts a parameter which implements Read trait. But tokio::net::TcpStream implements AsyncRead which is not compatible to be passed in Acceptor. Or may be I don't know how to use that.

Any guidance or minimal example is appreciated on how to use Acceptor.

If there are any better ways to implement dynamic server certificates fetched from a key store, I would like to know that too.

PS: I need TCP socket stream directly as I am implementing a Pub/Sub Broker both for experimentation and learning Rust for real use case.

No repository file or test is named. Start by reading the linked Rustls ServerConfig documentation and inspecting tokio-rustls's existing examples for Tokio TCP streams and server setup. Done means adding a minimal, working Acceptor example that shows dynamic certificate selection and can be followed by a newcomer.
