Description

Implementation of a write pipe stream.

`basic_opstream` public construct/copy/destruct

```
basic_opstream();
```
Default constructor.

basic_opstream(const basic_opstream &) = delete;

Copy constructor.

basic_opstream(basic_opstream &&) = default;

Move constructor.

```
basic_opstream(pipe_type && p);
```
Move construct from a pipe.
```
basic_opstream(const pipe_type & p);
```
Copy construct from a pipe.

basic_opstream & operator=(const basic_opstream &) = delete;

Copy assignment.

basic_opstream & operator=(basic_opstream &&) = default;

Move assignment.

basic_opstream & operator=(pipe_type && p);

Move assignment of a pipe.

basic_opstream & operator=(const pipe_type & p);

Copy assignment of a pipe.

`basic_opstream` public member functions

basic_pipebuf< CharT, Traits > * rdbuf() const;

Get access to the underlying stream_buf.

```
void pipe(pipe_type && p);
```
Set the pipe of the streambuf.
```
void pipe(const pipe_type & p);
```
Set the pipe of the streambuf.
```
pipe_type & pipe();
```
Get a reference to the pipe.
```
const pipe_type & pipe() const;
```
Get a const reference to the pipe.
```
pipe_type && pipe();
```
Get a rvalue reference to the pipe. Qualified as rvalue.
