mobi 0.8.0

//! An implementation of [MOBI](https://wiki.mobileread.com/wiki/MOBI) format data parsing and manipulation, written in Rust.
//!
//! The code is available on [GitHub](https://github.com/vv9k/mobi-rs)
//!
//! License: [*MIT*](https://github.com/vv9k/mobi-rs/blob/master/license)
//!
//! ## Examples
//! ### Access basic info
//! ```no_run
//! use mobi::{Mobi, MobiError};
//! fn main() -> Result<(), MobiError> {
//!     let book = vec![0, 0, 0];
//!     // You can either create a Mobi struct from a slice
//!     let m = Mobi::new(&book)?;
//!     // Or from an instance of io::Read
//!     let stdin = std::io::stdin();
//!     let mut handle = stdin.lock();
//!     let m = Mobi::from_read(&mut handle)?;
//!     // Or from filesystem
//!     let m = Mobi::from_path("/some/path/to/book.mobi")?;
//!
//!     // Access metadata
//!     let title = m.title();
//!     let author = m.author().unwrap_or_default();
//!     let publisher = m.publisher().unwrap_or_default();
//!     let desc = m.description().unwrap_or_default();
//!     let isbn = m.isbn().unwrap_or_default();
//!     let pub_date = m.publish_date().unwrap_or_default();
//!     let contributor = m.contributor().unwrap_or_default();
//!
//!     // Access Headers
//!     let metadata = &m.metadata;
//!     let header = &metadata.header; // Normal Header
//!     let pdheader = &metadata.palmdoc; // PalmDOC Header
//!     let mheader = &metadata.mobi; // MOBI Header
//!     let exth = &metadata.exth; // Extra Header
//!
//!     // Access content
//!     let content = m.content_as_string();
//!
//!     Ok(())
