Insert a copy of `value` at `position`.

== Synopsis

Declared in `<bslstl_vector.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
xref:bsl/vector-00d/iterator.adoc[vector<VALUE_TYPE, ALLOCATOR>::iterator]
insert(
    xref:bsl/vector-00d/const_iterator.adoc[const_iterator] position,
    VALUE_TYPE const& value);
----

== Description

Insert at the specified `position` in this vector a copy of the specified `value`, and return an iterator referring to the newly inserted element. If an exception is thrown (other than by the copy constructor, move constructor, assignment operator, or move assignment operator of `VALUE_TYPE`), `*this` is unaffected. Throw `std::length_error` if `size() == max_size()`. The behavior is undefined unless `position` is an iterator in the range `[begin() .. end()]` (both endpoints included). This method requires that the (template parameter) type `VALUE_TYPE` be `copy‐insertable` into this vector (see {Requirements on `VALUE_TYPE`}).

== Return Value

iterator referring to the newly inserted element

== Parameters
