Cindermark — High-Performance Incremental Markdown Parser

A Rust-native markdown parser designed for real-time editing in native iOS/macOS text editors. Cindermark is the engine that powers the editor in Ember Notes. Features:

• Single-pass lexer + parser producing block + inline AST
• SIMD-accelerated byte scanning via memchr
• UTF-8 to UTF-16 offset mapping for NSTextStorage compatibility
• UniFFI-generated Swift bindings (zero manual C bridging)
• Incremental dirty-region tracking (partial re-parse of edited blocks)

Modules

ast

AST node types for the Cindermark Markdown parser.

incremental

Incremental parse: dirty-block detection and partial re-parse.

inline

Inline span parser using a delimiter-run algorithm.

lexer

SIMD-accelerated UTF-8 byte scanner producing a token stream.

parser

Block-level parser producing a Document from source text.

utf16

UTF-8 to UTF-16 offset mapping.

Structs

CindermarkParser

The main parser object exposed to Swift via UniFFI.

FfiBlock

A block for FFI transport.

FfiDocumentStats

Document-level statistics computed as a byproduct of parsing — zero extra cost. Eliminates ~6 separate Swift string-scanning passes.

FfiHeading

A heading extracted from the document (level + text).

FfiIncrementalResult

Incremental parse result with dirty block range.

FfiIncrementalStyleResult

Lightweight incremental result for the styling-only path. Identical to FfiIncrementalResult but omits stats, avoiding the O(n) grapheme iteration + byte scan that compute_stats performs on every call. Used by the editor’s 400ms restyle timer where stats aren’t needed.

FfiInlineSpan

An inline span for FFI transport.

FfiListItem

A list item for FFI transport.

FfiParseResult

Parse result for FFI transport.

FfiPreviewSpan

A single inline span in a rendered preview.

FfiRenderedPreview

Rendered preview result: plain text with markdown syntax stripped, plus inline span ranges for rich formatting.

FfiSaveParseResult

Combined parse + preview result. Single parse pass produces everything needed for note save: AST, stats, wiki links, headings, and rich previews.

Enums

FfiBlockType

Block type enum for FFI.

FfiInlineType

Inline type enum for FFI.
