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");
}
}
}
