serialize_block()WP 5.3.1

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 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.
