## What it is
pulldown-cmark is a fast, memory-efficient pull parser for CommonMark Markdown written in pure Rust, with an included CLI tool for rendering to HTML. It supports GFM extensions like tables, task lists, strikethrough, footnotes, admonitions, and math, plus source-map information.

## Use cases
- parse markdown into html in rust
- render commonmark documents
- convert markdown files to html from the command line
- build a static site generator with markdown support
- extract structure and offsets from markdown with source maps
- parse github-flavored markdown tables and task lists
- process markdown with minimal memory allocation

## When to choose
- you need a fast, spec-compliant CommonMark parser in Rust
- memory usage matters and you want pull parsing instead of building a full AST
- you need source-map offsets between parsed blocks and original text
- you want GFM extensions like tables, footnotes, and strikethrough

## When to avoid
- you need an AST-based parser with tree manipulation
- you need Markdown flavors beyond CommonMark/GFM such as MultiMarkdown
- you are not working in Rust and need bindings in another language

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, cli
- domain: parsers, web-development, developer-tools, documentation
- platform: rust, cli, cross-platform
