 Interacting with Neovim's lua api in Rust can be a bit of a pain. `nvim-utils` aims to make it easier and quicker to develop Neovim plugins in Rust by removing as much of the required boilerplate as possible, and implementing bindings for the `vim.*` lua api.

+> This library is in a relatively early state and will change significantly.
+> For a more polished API, check out [nvim-oxi](https://github.com/noib3/nvim-oxi)

+- Integrate with the Luajit and Neovim C APIs directly
+- Minimize dependencies
