[section:insert insert]

[heading Prototype]

``
template<
    class Container,
    class SinglePassRange
    >
Container& insert(Container& target,
                  typename Container::iterator before,
                  const SinglePassRange& from);
``

[heading Description]

`insert` all of the elements in the range `from` before the `before` iterator into `target`.

[heading Definition]

Defined in the header file `boost/range/algorithm_ext/insert.hpp`

[heading Requirements]

# `SinglePassRange` is a model of the __single_pass_range__ Concept.
# `Container` supports insert at a specified position.
# `SinglePassRange`'s value type is convertible to `Container`'s value type.

[heading Complexity]

Linear. `distance(from)` assignments are performed.
