#![cfg_attr(docsrs, feature(doc_cfg))]
//! # Utilities for building Neovim plugins in Rust<br>
//! The intention of `nvim-utils` is to allow Rust plugin authors to interact with Neovim in Rust just as easily as in Lua,<br>
//! by removing as much of the required boilerplate as possible.
//!
//! It provides utilities for:
//! - Declaratively building lua modules using `mlua`
//! - Interacting with Neovim's lua api
//! - Logging using `vim.notify`
//! - Accessing common lua builtin functions like `require` and `print`
//! - And more to come!
//!
//! #### Features
//! - `builder` enables the [`builder`] module, containing [`ModuleBuilder`](struct@builder) (enabled by default)
//! - `vim` enables the [`vim`] module (enabled by default)
//! - `async` enables async functions in [`builder::ModuleBuilder`], and the `async` feature in mlua (disabled by default)
//! - `send` enables the `send` feature for [`mlua`], which enables `Send` for lua types (disabled by default)
//! - `unstable` includes unstable / untested API features (disabled by default)

/// Includes [`mlua::prelude`], [`vim`], [`vim::ext::log`], and [`builder::ModuleBuilder`] if the corresponding features are enabled
