array::insert (2 of 5 overloads)

Insert elements before the specified location.

Synopsis

iterator
insert(
    const_iterator pos,
    value&& v);

This inserts v before pos via move-construction. If capacity() < size() + 1, a reallocation occurs first, and all iterators and references are invalidated. Otherwise, only the iterators and references from the insertion point forward are invalidated. All past-the-end iterators are also invalidated.

Complexity

Constant plus linear in std::distance(pos, end()).

Exception Safety

Strong guarantee. Calls to memory_resource::allocate may throw.

Parameters

Name	Description
`pos`	Iterator before which the content will be inserted. This may be the `end()` iterator.
`v`	The value to insert. Ownership of the value will be transferred via move construction, using the container's associated `boost::container::pmr::memory_resource`.

Return Value

An iterator to the inserted value
