Termify::Markdown::Renderer

-- lifecycle ---------------------------------------------------------

Resets the renderer (see #reset) and marks the renderer closed.

Returns true if this IO is closed.

IO defines returns false, but including types may override.

Accepts the next chunk of Markdown. May be any size -- a single byte up to the entire document. Raises if called after #close.

Renderer is write-only; reading always raises.

Flushes any buffered content AND resets the renderer, closing off any block/list/blockquote/table states. The ensure is what makes the Started/Finished pairing a guarantee rather than an intention: it covers close, an early reset, and an exception raised mid-table.

-- IO abstract interface --------------------------------------------- Decodes slice as UTF-8 Markdown and feeds it into the renderer. Caller guarantees valid UTF-8.
