//! # Semi-direct mapping of the `vim` module in Neovim's lua api
//!
//! The goal for this module is to provide an idiomatic way to call Neovim's lua api from Rust, without needing to repeat the boilerplate for loading specific functions.
//!
//! Notable differences from the lua api:
//! - `vim.fn` has been renamed to `vim::func`, since fn is a keyword in Rust
//! - Added `vim::ext` for functions that don't directly map to the Neovim api but make use of it or extend it
//! - Not all functions are implemented yet

pub mod ext;
pub mod func;
