Defined at:


Returns the content of a block, including comment delimiters, serializing all attributes from the given parsed block.This should be used when preparing a block to be saved to post content. Prefer `render_block` when preparing a block for display. Unlike `render_block`, this does not evaluate a block's `render_callback`, and will instead preserve the markup as parsed.
