//! A simple benchmark which tries to parse a list of off documents.
//!
//! The results of the benchmark are **not** compared against other libraries
//! but instead are used to check/test against regressions.
//!
//! # Run
//!
//! To run the benchmark run the following in a terminal:
//!
//! ```bash
//! cargo bench parse
//! ```
