surf-parse 0.10.0

//! `surf-parse` — parser for the SurfDoc format.
//!
//! SurfDoc is a typed document format with block directives, embedded data,
//! and presentation hints. Backward-compatible with Markdown. This crate
//! provides the foundational parser that turns `.surf` source text into a
//! structured `SurfDoc` tree.
//!
//! # Quick start
//!
//! ```
//! let result = surf_parse::parse("# Hello\n\n::callout[type=info]\nHi!\n::\n");
//! assert!(result.diagnostics.is_empty());
//! assert_eq!(result.doc.blocks.len(), 2);
//! ```
