# Extending Emacs in Rust with Dynamic Modules
Tuấn-Anh Nguyễn

Dynamic module support has been available since Emacs 25. It can be
used to extend Emacs with native libraries, for performance,
OS-specific features, or other functionalities that would take a lot
of time to re-implement in Lisp. The officially supported language is
C, which is tedious and error-prone to use. This talk discusses a
**safe** alternative that is also a lot **more convenient**: writing these
dynamic modules in Rust.



# Outline

-  Walking through creating **a simple dynamic module** in
    Rust, including setting up CI.
-  Going through and explaining the **available APIs**.
<!---   40 minutes: All of the above, together with reporting the experience
    of using it in real packages (e.g. tree-sitter), as well as
    discussing **challenges and potential improvements** to dynamic modules
    in general.-->
