cratesland/spath: Query expressions for semi-structured data

You can use it as a drop-in replacement for JSONPath, but also for other semi-structured data formats like TOML or user-defined variants.

Here is a quick example that shows how to use the spath crate to query JSONPath alike expression over JSON data:

use serde_json::json;
use serde_json::Value as JsonValue;
use spath::SPath;
use spath::Value;

fn main() {
    let data = json!({
        "name": "John Doe",
        "age": 43,
        "phones": [
            "+44 1234567",
            "+44 2345678"
        ]
    });

    let spath = SPath::new("$.phones[1]").unwrap();
    let value = Value::from(data);
    let result = spath.eval(&value).unwrap();
    assert_eq!(JsonValue::from(result), json!("+44 2345678"));
}

spath is on crates.io and can be used by adding spath to your dependencies in your project’s Cargo.toml. Or more simply, just run cargo add spath.
