+# mqtt-exporter-rs
+
+A reimplementation of [mqtt-exporter](https://github.com/kpetremann/mqtt-exporter) in Rust. That's pretty much the gist of it. I was having issues with memory leaks in the Python implementation so I spun this together. It works for my purposes but is far from tested.
+
+I slightly modified the logic, since I don't understand why some of the topic munging is done and would prefer to keep the topics as-is.
