quillmark_content/lib.rs
1//! `Content`: the canonical content model for Quillmark.
2//!
3//! One [`model::Content`] per content field: a single text sequence carrying
4//! line attributes, anchored marks, and embedded islands, over one coordinate
5//! space of Unicode scalar values. Markdown is a *projection*
6//! ([`import::from_markdown`], [`export::to_markdown`]), so every edit is a
7//! splice and all structure moves with it. [`serial`] is the canonical,
8//! byte-deterministic JSON that storage, the render seam and the binding seam
9//! all carry; [`delta`] and [`ops`] are the per-field edit surface.

30/// The recursive consumers (key sorting, `serde_json::Value`'s own `Drop`) spend
31/// a frame per level, so an unbounded bag overflows the stack: on wasm32 an

33/// own limit, so nothing a stored blob can carry is refused.
