//! Structured access to the Dependabot configuration.
//!
//! ## Examples
//!
//! ```rust
//! # fn dox() -> std::io::Result<()> {
//! use std::fs;
//!
//! use dependabot_config::v2::Dependabot;
//!
//! let s = fs::read_to_string(".github/dependabot.yml")?;
//! let dependabot: Dependabot = s.parse()?;
//! for update in dependabot.updates {
//!     println!("{}", update.package_ecosystem);
//! }
//! # Ok(())
//! # }
//! ```
