Description

Generate JSON output incrementally by appending C++ data.

`basic_writer` public construct/copy/destruct

```
template<typename T> basic_writer(T & buffer);
```
Construct an incremental JSON writer.
The buffer type can be any for which a buffer wrapper exists.

Parameters:

buffer

A buffer where the JSON formatted output is stored.

`basic_writer` public member functions

```
std::error_code error() const noexcept;
```
```
size_type level() const noexcept;
```
```
template<typename T> size_type value();
```
Write structural output.

template<typename T> size_type value(T && value);

Write data output.

size_type literal(const view_type &) noexcept;

Write raw output.
