operator params_view() const;
This conversion returns a new view which references the same underlying character buffer, and whose iterators and members return ordinary strings with decoding applied to any percent escapes. Ownership is not transferred; the caller is responsible for ensuring the lifetime of the buffer extends until it is no longer referenced.
params_view qp = parse_path( "/path/to/file.txt" ).value();
params_view( *this ).buffer().data() == this->buffer().data()
