//! # c3dio - Pure Rust C3D Parser
//! This crate provides a parser for C3D files.
//! C3D is a binary file format used to store motion capture data.
//! The format is described in the [C3D file format documentation](https://www.c3d.org/HTML/default.htm).
//!
//! # Examples
//! ```
//! use c3dio::prelude::*;
//!
//! let c3d = C3d::load("tests/data/short.c3d");
//! assert!(c3d.is_ok());
//! ```
