Crate sim_codec_doc 

Document domain codec for SIM.

Provides codec:doc, a domain decoder/encoder pair that turns document text (plain or Markdown) into a structured document Expr and back, plus 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):

• codec: the DocCodec decoder/encoder, the DocCodecLib host lib, and install_doc_codec.
• document: the document model (DocValue, DocFormat, DocBlock, DocChunk, ChunkOp), decode_document, and the chunk operation.
• functions: the doc/chunk-* chunking functions registered as callables.

Structs

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.

Enums

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.

Statics

RECIPES

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

Functions

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.

install_doc_codec

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