yjs-html-core

Internal core of lexical-yjs-html and prosemirror-yjs-html: the per-node render rules and segmented HTML output they share.

Don't depend on this crate directly. The renderer crates re-export its whole surface (Rules, Segment, flatten, and the rest), and it makes no stability promise of its own. It's a separate package only because published crates can't share a path dependency.

Rules come in two tiers. A declarative rule (tag, attributes, text, content slot) compiles to NodeRule/MarkRule and renders inside the transaction. A callback rule defers to the caller: the renderer emits Segment::Deferred with the node's type, attributes as JSON, and its rendered children, and you splice the result in after the render returns. Your code never runs while the document is locked. Rules parse from one JSON document (Rules::parse), so the same format works for any binding.
