Crate sim_codec_doc 

Markup document domain codec for SIM.

Provides codec:doc, a domain decoder/encoder pair that turns document text into a semantic markup document Expr and back, strict codec:markup/<id> backends for Markdown, Typst, AsciiDoc, and LaTeX, and provenance-preserving chunk operations exposed as callable functions. As a domain codec it round-trips only documents and chunks and fails closed outside that domain.

Module map (all modules are private; the public surface is re-exported from this crate root):

• backend: the MarkupBackend trait, deterministic BackendRegistry, and fidelity/error contracts for backend implementations.
• catalog: the implemented/tracked backend catalog for markup formats.
• codec: the DocCodec decoder/encoder, the DocCodecLib host lib, and install_doc_codec plus codec:markup/<id> installation.
• document: compatibility chunking wrappers (DocValue, DocFormat, DocBlock, DocChunk, ChunkOp), decode_document, and chunk.
• edit: reversible document-domain edits over MarkupDoc.
• markup: the shared semantic markup IR (MarkupDoc, MarkupBlock, Inline) and its ordinary-data projection.
• functions: the doc/chunk-* chunking functions registered as callables.
• asciidoc: the asciidork-parser AsciiDoc backend.
• latex: the codebook-tree-sitter-latex LaTeX backend.
• markdown: the pulldown-cmark Markdown backend.
• typst_backend: the typst-syntax Typst backend.

Structs

AsciiDocBackend

Safe AsciiDoc markup backend.

BackendId

A backend identifier such as markdown, typst, asciidoc, or latex.

BackendInfo

Catalog row describing one markup backend or tracked format.

BackendRegistry

Deterministic registry of markup backends.

BasicMarkdownBackend

Compatibility name for the default Markdown backend.

DocBlock

One parsed span of a document, carrying its byte offsets and the heading path in effect where it appears.

DocChunk

A provenance-preserving slice of a document produced by chunk.

DocCodec

The codec:doc decoder/encoder.

DocCodecLib

The host-registered Lib that installs DocCodec as codec:doc and the doc/chunk-* chunking functions.

DocValue

A decoded document: its full source text, detected format, and the ordered DocBlocks parsed from it.

LatexBackend

Safe LaTeX article-subset backend.

MarkdownBackend

CommonMark/GFM-compatible Markdown backend.

MarkupCodec

Strict runtime codec for one markup backend.

MarkupDecodeOptions

Decode options shared by markup backends.

MarkupDoc

A semantic markup document independent of its concrete source backend.

MarkupEncodeOptions

Encode options shared by markup backends.

MarkupFidelity

Fidelity report returned by markup backends.

MarkupLoss

A single lossy conversion note.

MathSource

Markup math source with a notation label.

SourceDoc

A concrete source document preserved alongside the semantic IR.

Span

A source span in byte offsets.

TypstBackend

Safe Typst markup backend.

Enums

BackendStatus

Implementation state for a cataloged markup backend.

ChunkOp

A chunking strategy selecting how chunk splits a DocValue.

DocBlockKind

The category of a DocBlock.

DocFormat

The detected surface format of a decoded document.

Inline

Inline content in a markup document.

MarkupBlock

A semantic block in a markup document.

MarkupEdit

A reversible edit over a semantic markup document.

MarkupError

Error returned by markup backend and registry operations.

SpanState

Source-span freshness after reversible document edits.

Constants

MARKUP_CODEC_PREFIX

Textual prefix for rendered markup codec symbols.

Statics

RECIPES

Cookbook recipes embedded from this crate’s recipes/ directory.

Traits

MarkupBackend

A concrete markup reader/writer behind a runtime codec id.

Functions

apply_edit

Apply a reversible markup edit to a document.

backend_catalog

Return the deterministic catalog of implemented and tracked markup backends.

chunk

Split a decoded doc into DocChunks according to op.

decode_document

Parse document text into a DocValue, recording per-block byte offsets and heading paths.

decode_markup_doc

Decode source text into the shared markup IR using the current lightweight document parser.

default_backend_registry

Build the default registry installed by install_doc_codec.

install_doc_codec

Install DocCodecLib into cx, registering codec:doc and the doc/chunk-* functions with a freshly allocated codec id.

install_markup_codecs

Install each registered markup backend as codec:markup/<id>.

invert_edit

Return the inverse edit for edit.

markup_codec_symbol

Return the runtime codec symbol for a markup backend id.
