egui_commonmark offers experimental support for using comrak as parsing backend. By default pulldown_cmark is used. To use comrak instead do:
egui_commonmark = { version = "0.14", default-features = false, features = ["load-images", "comrak"] }egui_commonmark was originally implemented using pulldown_cmark, however comrak has stricter commonmark/github style markdown support. In addition it allows the crate to support more features than pulldown_cmark can offer with regards to github style markdown.
pulldown_cmark has fewer dependencies and should theoretically be faster.
Due to these reasons both backends are supported. At least for now. If you are unsure of what to use, just use pulldown_cmark the default backend.
The comrak backend does not support Alerts due do them being difficult to implement with comrak
