  Nowaday, thanks to [`reqwest`](https://docs.rs/reqwest/0.10.1/reqwest/#proxies), `rspotify` now supports system proxy by default. `Reqwest` System proxies look in environment variables to set HTTP or HTTPS proxies. `HTTP_PROXY` or `http_proxy` provide http proxies for http connections while `HTTPS_PROXY` or `https_proxy` provide HTTPS proxies for HTTPS connections.(~~Notes that `reqwest` system proxy doesn't support socks proxy for now,~~ check [this issue](https://github.com/seanmonstar/reqwest/issues/790) for more details)
