Dial works like DialContext on net.Dialer but using a dialer returned by FromEnvironment.

FromEnvironment returns the dialer specified by the proxy-related variables in the environment and makes underlying connections directly.

FromEnvironmentUsing returns the dialer specify by the proxy-related variables in the environment and makes underlying connections using the provided forwarding Dialer (for instance, a *net.Dialer with desired configuration).

FromURL returns a Dialer given a URL specification and an underlying Dialer for it to make network requests.

NewPerHost returns a PerHost Dialer that directs connections to either defaultDialer or bypass, depending on whether the connection matches one of the configured rules.

RegisterDialerType takes a URL scheme and a function to generate Dialers from a URL with that scheme and a forwarding Dialer.

SOCKS5 returns a Dialer that makes SOCKSv5 connections to the given address with an optional username and password.

Direct implements Dialer by making network connections directly using net.Dial or net.DialContext.

Auth contains authentication parameters that specific Dialers may require.

A PerHost directs connections to a default Dialer unless the host name requested matches one of a number of exceptions.

A ContextDialer dials using a context.

A Dialer is a means to establish a connection.
