Implementation of the QUIC transport protocol for libp2p.
# Usage
Example:
```
# #[cfg(not(feature = "async-std"))]
# fn main() {}
#
# #[cfg(feature = "async-std")]
# fn main() -> std::io::Result<()> {
#
use libp2p_quic as quic;
use libp2p_core::{Multiaddr, Transport};
let keypair = libp2p_core::identity::Keypair::generate_ed25519();
let quic_config = quic::Config::new(&keypair);
let mut quic_transport = quic::async_std::Transport::new(quic_config);
let addr = "/ip4/127.0.0.1/udp/12345/quic-v1".parse().expect("address should be valid");
quic_transport.listen_on(addr).expect("listen error.");
#
# Ok(())
# }
```
The [`GenTransport`] struct implements the [`libp2p_core::Transport`]. See the
documentation of [`libp2p_core`] and of libp2p in general to learn how to use the
[`Transport`][libp2p_core::Transport] trait.
Note that QUIC provides transport, security, and multiplexing in a single protocol. Therefore,
QUIC connections do not need to be upgraded. You will get a compile-time error if you try.
Instead, you must pass all needed configuration into the constructor.
