##### Description

The primary interface for incremental SQL formatting. Contrary to `format_context_base`, this type is aware of the output string's actual type. `basic_format_context` owns an instance of `OutputString`. Format operations will append characters to such string.

Objects of this type are single-use: once the result has been retrieved using `get`, they cannot be re-used. This is a move-only type.
