| Parameter | Requirement | Description |
|---|---|---|
| Seq | Front Extensible Sequence | A sequence to bind the inserter to. |
The semantics of an expression are defined only where they differ from, or are not defined in Inserter.
For any Front Extensible Sequence s:
| Expression | Semantics |
|---|---|
| front_inserter<s> | An Inserter in, equivalent to struct in : inserter<s,push_front<_1,_2> > {}; |
Amortized constant time.
