//! Functionality for reading CSV files.
//!
//! # Examples
//!
//! ```
//! use polars_core::prelude::*;
//! use polars_io::prelude::*;
//! use std::fs::File;
//!
//! fn example() -> PolarsResult<DataFrame> {
//!     // Prefer `from_path` over `new` as it is faster.
//!     CsvReadOptions::default()
//!         .with_has_header(true)
//!         .try_into_reader_with_file_path(Some("example.csv".into()))?
//!         .finish()
//! }
//! ```
