//! [![Build Status](https://github.com/rscarson/font-map/actions/workflows/tests.yml/badge.svg?branch=master)](https://github.com/rscarson/font-map/actions?query=branch%3Amaster)

//!
//! This crate provides an enum of all the glyphs in the `JetbrainsMono Nerd Font`.  
//! Additionally, it provides a way to load the font, and QOL features for using the font in iced.
//!
//! In addition - you can hover over the icons in your IDE to see a preview of the icon!
//!
//! See <https://www.nerdfonts.com/> for more information
//!
//! **I am not affiliated with Nerd Fonts, nor do I have any rights to the `JetbrainsMono Nerd Font`.**  
//! This crate is published with a copy of the font, and its license, as allowed by the license.
//!
//! See [`NerdFont`] or [`categories`] for the list of available icons, including their names, codepoints and a preview image.  
//!
//! -----
//!
//! The individual glyphs are in seperate enums inside of the [`categories`] module:
//! ```rust
//! use nerd_font::categories;
//!
//! let _ = categories::Dev::Android;
//! let _ = categories::Fa::ArrowLeft;
//! ```
//!
//! There is also an enum encapsulating all the glyphs, [`NerdFont`], which can be converted to and from the individual enums:
//! ```rust
//! use nerd_font::{NerdFont, categories::Dev};
//! let _: NerdFont = Dev::Android.into();
//! ```
//!
//! -----
//!
//! Each glyph contains the following information:
//! - Unicode codepoint: e.g. `Dev::Android as u32`
//! - Postfix name: e.g. `Dev::Android.name()`
//! - Glyph preview image, visible in the documentation, and by hovering over the glyphs in your IDE!
//!
//! You can also get the actual char from the enum, with `char::from(Dev::Android)`, or `Dev::Android.to_string()`
//!
//! -----
//!
//! If you use `iced` there are some QOL features built-in:  
//! **NOTE: ** you will need to activate the `iced` crate-level feature to use these!
//!
//! - [`NerdFont::FONT_BYTES`] is the raw bytes of the font, for loading into iced
//! - [`IcedExt`] provides the helper functions for using the font in iced
//! - `NerdFont` also implements `Into<iced::Element>`, which will use the default font size
//!
//! ```ignore
//! use nerd_font::{IcedExt, categories::Dev};
//!
//! // A text widget configured to use the icon font, with the selected glyph, and a font size of 24
//! let text_widget = Dev::Android.into_text(24);
//! ```
//!
//! You will additionally need to load the font, by calling `.font(NerdFont::FONT_BYTES)` on your `iced::Application`.
//!
//! ## Crate Features
//!
//! #### `iced`
//! Default: Off  
//! Provides some QOL features for using the font in iced, including a font definition, and conversion to an iced Text widget.
