Crate moss_core 

moss-core: Pure Rust content processing.

Zero I/O, zero async. Takes strings in, returns strings out. All filesystem access happens in the Tauri layer.

Panic-free contract: Every public function in moss-core is invoked from Tauri command handlers in the host process. The host is configured with panic = "abort" for release builds, so any panic on user input crashes the whole desktop app (see fix in date.rs for the editor-mount panic on Chinese filenames). Treat moss-core as panic-free on user input: never unwrap/expect a value derived from arbitrary user data, and never use byte-indexed &str slicing without a char_boundary guarantee.

Modules

asset_paths

Pure URL/path transform helpers — no filesystem access, no env lookups. Used by moss-core’s render functions (see crate::render::*) and by upstream src-tauri call sites.

asset_snapshot

Pre-fetched asset metadata available to Stage 1 + Stage 2.

ast

Typed body AST.

content_graph

In-memory index of content files, headings, and block IDs.

contract

moss HTML/CSS contract surface.

csv_table

Pure CSV/TSV → HTML table renderer.

date

Publish-date resolution for moss content.

extract_headings

Pure extraction of a document’s headings (text + slug + level) for the editor’s [[Page#Heading]] autocomplete. Reuses parse() (which runs assign_heading_id_suffixes) so the returned slugs are byte-identical to the rendered <hN id="..."> attributes — the keystone invariant.

frontmatter

YAML frontmatter parsing with body preservation.

frontmatter_union

Normalization for union-typed frontmatter fields (children, series).

heading

Article heading rule — single source of truth for the auto-injected <h1 class="moss-article-title"> and the editor’s pinned heading element.

heading_anchor

Obsidian-compatible heading anchor generation.

home

Home file detection for the moss content model.

link_candidates

Link resolution candidate generation.

link_completions

Pure ranker for wikilink autocomplete completions.

media

Unified media reference resolution and display attributes.

page_kind

Classification of moss page/source-file kinds.

render

HTML synthesizers for moss-emitted markdown content.

resolve

Centralized link resolution — ALL wikilink handling (body AND frontmatter) happens here.

resolved

A value paired with its origin. Lets downstream consumers decide whether to honor the value as author intent (explicit) or override it with an inferred default (auto-detected).

schema

Content model types driven by the schema.

schema_fields

Builtin frontmatter field definitions.

shortcode_tokens

Tokenizer for shortcode opening, closing, and divider lines.

sort

Folder-listing sort: types and inference cascade.

validation

Schema-driven frontmatter validation.
