Constructor
<boost/url/params_ref.hpp>
params_ref(
    params_ref const& other,
    encoding_opts opt) noexcept;
After construction, both views will reference the same url but this instance will use the specified encoding_opts when the values are decoded.
Ownership is not transferred; the caller is responsible for ensuring the lifetime of the url extends until it is no longer referenced.
&this->url() == &other.url()
Constant.
Throws nothing.
