void push_front( const T& value );
void push_front( T&& value );		(since C++11)

Prepends the given element value to the beginning of the container.

All iterators, including the past-the-end iterator, are invalidated. No references are invalidated.

Parameters

value

-

the value of the element to prepend

Return value

(none)

Complexity

Constant.

Exceptions

If an exception is thrown, this function has no effect (strong exception guarantee).
