Files Transform

Rust equivalent of the Python files_transform example.

It walks a directory of markdown files, memoizes the markdown-to-HTML transform per file, and writes one HTML file per markdown input.

Build

cd examples/rust/files_transform
cargo build --release

Usage

Run against the sample data from the Python example:

cargo run -- ../../files_transform/data ./output_html

Defaults:

• source dir: ../../files_transform/data
• output dir: ./output_html

Notes

• The markdown→HTML render is memoized, so unchanged inputs skip the work.
• Output uses a declarative DirTarget (the Rust analogue of Python's localfs directory target): files are written/updated, unchanged files are skipped, and an output whose source markdown was deleted is removed automatically on the next run.
• Like the Python example (whose walk_dir defaults to recursive=False), only top-level *.md files are processed.
• Markdown rendering uses pulldown-cmark with GFM options (tables, strikethrough, tasklists). It is not byte-identical to Python's markdown-it-py("gfm-like") — notably, pulldown-cmark does not "linkify" bare URLs (only angle-bracket <https://…> autolinks render).
