//! Find out the path at which a deserialization error occurred. This crate
//! provides a wrapper that works with any existing Serde `Deserializer` and
//! exposes the chain of field names leading to the error.
//!
//! # Example
//!
//! ```
//! # use serde_derive::Deserialize;
//! #
//! use serde::Deserialize;
//! use std::collections::BTreeMap as Map;
//!
//! #[derive(Deserialize)]
//! struct Package {
//!     name: String,
//!     dependencies: Map<String, Dependency>,
//! }
//!
//! #[derive(Deserialize)]
//! struct Dependency {
//!     version: String,
//! }
//!
//! fn main() {
//!     let j = r#"{
//!         "name": "demo",
//!         "dependencies": {
//!             "serde": {
//!                 "version": 1
//!             }
//!         }
//!     }"#;
//!
//!     // Some Deserializer.
//!     let jd = &mut serde_json::Deserializer::from_str(j);
//!
//!     let result: Result<Package, _> = serde_path_to_error::deserialize(jd);
//!     match result {
//!         Ok(_) => panic!("expected a type error"),
//!         Err(err) => {
//!             let path = err.path().to_string();
//!             assert_eq!(path, "dependencies.serde.version");
//!         }
//!     }
//! }
