Insert segments.

Synopsis

iterator
insert(
    iterator before,
    std::initializer_list< string_view > init);

Description

This function inserts the segments in an initializer list before the specified position. Reserved characters in the list are percent-escaped in the result.

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

Remarks

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

Example

url u( "/file.txt" );

u.segments().insert( u.segments().begin(), { "path", "to" } );

Complexity

Linear in init.size() + this->url().encoded_resource().size().

Exception Safety

Strong guarantee. Calls to allocate may throw.

Return Value

An iterator to the first element inserted, or before if init.size() == 0.
