Function connect_random 

pub async fn connect_random(
    network: NetworkType,
    cert_path: &str,
    key_path: &str,
) -> Result<Peer>

Connects to a random peer on the specified network (Rust API version).

The function performs DNS lookups using the network’s introducers, picks a random address from the returned list, and attempts to establish a connection. It will try every resolved address until a connection succeeds.
