segments_ref::insert (3 of 3 overloads)

Insert segments.

template<
    class FwdIt>
iterator
insert(
    iterator before,
    FwdIt first,
    FwdIt last);

This function inserts the segments in a range before the specified position. Reserved characters in the list are automatically escaped.

All iterators that are equal to before or come after are invalidated.

None of the character buffers referenced by the range may overlap the character buffer of the underlying url, or else the behavior is undefined.

std::is_convertible< std::iterator_traits< FwdIt >::reference_type, string_view >::value == true

Linear in std::distance( first, last ) + this->url().encoded_resource().size().

Strong guarantee. Calls to allocate may throw.

An iterator to the first segment inserted, or before if init.empty().

Name	Description
`before`	An iterator before which the range will be inserted. This may be equal to `end()`.
`first`, `last`	The range of segments to insert.
