//! ISO 8211 (IHO transfer format) reader.
//!
//! This crate parses the **Data Descriptive Record** (schema) and **Data Records**
//! from ISO 8211 files, as used by IHO products such as S-57 ENC and S-101 datasets.
//!
//! # Example
//!
//! ```no_run
//! use iso8211::DataDescriptiveFile;
//!
//! let ddf = DataDescriptiveFile::read("path/to/file.000")?;
//! let _schema = ddf.data_descriptive_record();
//! let _rows = ddf.data_records();
//! # Ok::<(), iso8211::Iso8211Error>(())
//! ```
//!
//! See crate [`DataDescriptiveFile`] for the main entry point.
