segments::insert (3 of 3 overloads)

Insert a range of segments.

Synopsis

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

This function inserts a range of percent-encoded strings. Each string must contain a valid percent-encoding or else an exception is thrown. The behavior is undefined if either argument is an iterator into this. All references and iterators starting from the newly inserted elements and up to and including the last element and end iterators are invalidated.

Requires

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

Example

url u = parse_relative_uri( "/path/file.txt" );

segments se = u.segments();

std::vector< std::string > v = { "to", "the" };

se.insert( u.end() - 1, v.begin(), v.end() );

assert( u.encoded_path() == "/path/to/the/file.txt") );

Remarks

Behavior is undefined if any elements of the range belong to the container

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

Return Value

An iterator to one past the last newly inserted element or before if the range is empty.
