hickory-to-socket-addrs

The entry point is the HickoryToSocketAddrs struct, which wraps the host and port and use hickory-dns under the hood to perform DNS resolution instead of glibc's getaddrinfo which can block or has a lot of other known issues.

If this is run in a tokio context, we use it, otherwise we spawn a new tokio runtime to perform the query.

Example

use hickory_to_socket_addrs::HickoryToSocketAddrs;
use std::net::ToSocketAddrs;

let socket_addrs = "www.rust-lang.org:443"
    .parse::<HickoryToSocketAddrs<_>>()?
    .to_socket_addrs()?
    .collect::<Vec<_>>();
