}
// Values returns the url.Values encoding of v.
//
// Values expects to be passed a struct, and traverses it recursively using the
// following encoding rules.
//
// Each exported struct field is encoded as a URL parameter unless
//
// - the field's tag is "-", or
// - the field is empty and its tag specifies the "omitempty" option
//
// The empty values are false, 0, any nil pointer or interface value, any array
// slice, map, or string of length zero, and any time.Time that returns true
// for IsZero().
//
// The URL parameter name defaults to the struct field name but can be
// specified in the struct field's tag value. The "url" key in the struct
// field's tag value is the key name, followed by an optional comma and
// options. For example:
//
// // Field is ignored by this package.
// Field int `url:"-"`
//
// // Field appears as URL parameter "myName".
// Field int `url:"myName"`
//
// // Field appears as URL parameter "myName" and the field is omitted if
// // its value is empty
// Field int `url:"myName,omitempty"`
//
// // Field appears as URL parameter "Field" (the default), but the field
// // is skipped if empty. Note the leading comma.
// Field int `url:",omitempty"`
//
// For encoding individual field values, the following type-dependent rules
// apply:
//
// Boolean values default to encoding as the strings "true" or "false".
// Including the "int" option signals that the field should be encoded as the
// strings "1" or "0".
//
// time.Time values default to encoding as RFC3339 timestamps. Including the
// "unix" option signals that the field should be encoded as a Unix time (see
// time.Unix())
//
// Slice and Array values default to encoding as multiple URL values of the
// same name. Including the "comma" option signals that the field should be
// encoded as a single comma-delimited value. Including the "space" option
// similarly encodes the value as a single space-delimited string. Including
// the "semicolon" option will encode the value as a semicolon-delimited string.
// Including the "brackets" option signals that the multiple URL values should
// have "[]" appended to the value name. "numbered" will append a number to
// the end of each incidence of the value name, example:
// name0=value0&name1=value1, etc.
//
// Anonymous struct fields are usually encoded as if their inner exported
// fields were fields in the outer struct, subject to the standard Go
// visibility rules. An anonymous struct field with a name given in its URL
// tag is treated as having that name, rather than being anonymous.
//
// Non-nil pointer values are encoded as the value pointed to.
//
// Nested structs are encoded including parent fields in value names for
// scoping. e.g:
//
// "user[name]=acme&user[addr][postcode]=1234&user[addr][city]=SFO"
//
// All other values are encoded using their default string representation.

// Multiple fields that encode to the same URL parameter name will be included
