//! This module provides utility structs for loading and preprocessing files.
//!
//! The `FileLoader` struct can be used to define a common interface for loading any type of files from disk,
//! as well as performing minimal preprocessing on the files, such as reading their contents, ignoring errors
//! and keeping track of file paths along with their contents.
//!
//! The `PdfFileLoader` works similarly to the [FileLoader], but is specifically designed to load PDF
//! files. This loader also provides PDF-specific preprocessing methods for splitting the PDF into pages
//! and keeping track of the page numbers along with their contents.
//!
//! Note: The `PdfFileLoader` requires the `pdf` feature to be enabled in the `Cargo.toml` file.
//!
//! The `EpubFileLoader` works similarly to the `FileLoader`, but is specifically designed to load EPUB
//! files. This loader also provides EPUB-specific preprocessing methods for splitting the EPUB into chapters
//! and keeping track of the chapter numbers along with their contents.
//!
//! Note: The EpubFileLoader requires the `epub` feature to be enabled in the `Cargo.toml` file.
