type Dialer struct {
	fasthttp.TCPDialer
	// Support HTTPProxy, HTTPSProxy and NoProxy configuration.
	//
	// HTTPProxy represents the value of the HTTP_PROXY or
	// http_proxy environment variable. It will be used as the proxy
	// URL for HTTP requests unless overridden by NoProxy.
	//
	// HTTPSProxy represents the HTTPS_PROXY or https_proxy
	// environment variable. It will be used as the proxy URL for
	// HTTPS requests unless overridden by NoProxy.
	//
	// NoProxy represents the NO_PROXY or no_proxy environment
	// variable. It specifies a string that contains comma-separated values
	// specifying hosts that should be excluded from proxying. Each value is
	// represented by an IP address prefix (1.2.3.4), an IP address prefix in
	// CIDR notation (1.2.3.4/8), a domain name, or a special DNS label (*).
	// An IP address prefix and domain name can also include a literal port
	// number (1.2.3.4:80).
	// A domain name matches that name and all subdomains. A domain name with
	// a leading "." matches subdomains only. For example "foo.com" matches
	// "foo.com" and "bar.foo.com"; ".y.com" matches "x.y.com" but not "y.com".
	// A single asterisk (*) indicates that no proxying should be done.
	// A best effort is made to parse the string and errors are
	// ignored.
	httpproxy.Config
	// Attempt to connect to both ipv4 and ipv6 addresses if set to true.
	// By default, dial only to ipv4 addresses,
	// since unfortunately ipv6 remains broken in many networks worldwide :)
	//
	// This field from the fasthttp client is provided redundantly here because
	// when we customize the Dial function for the client, its DialDualStack field
	// configuration becomes ineffective.
	DialDualStack bool
	// Dial timeout.
	//
	// This field from the fasthttp client is provided redundantly here because
	// when we customize the Dial function for the client, its DialTimeout field
	// configuration becomes ineffective.
	Timeout time.Duration
	// The timeout for sending a CONNECT request when using an HTTP proxy.
