//! Module for mapping file types and names to Nerd Font icons.
//! This module provides functions to retrieve appropriate icons
//! based on file extensions, special filenames, and directory names.
//!
//! It uses `once_cell` for lazy static initialization of icon maps.
//! The icons are represented as static string slices.
//!
//! The main function `nerd_font_icon` takes a `FileEntry` and returns
//! the corresponding Nerd Font icon.
