Replace segments
iterator replace( iterator pos, core::string_view s);
This function replaces the segment at the specified position. Reserved characters in the string are automatically escaped.
All iterators that are equal to `pos` or come after are invalidated.
Linear in `s.size() + this->url().encoded_resouce().size()`.
Strong guarantee. Calls to allocate may throw.
