jsonpath_rs

A JSONPath library for rust. The idea behind this library is that it can operate on any json representation as long as it implements the SelectValue triat. The library has an implementation for serde_json value and ivalue.

Getting Started

Add the following to your cargo.toml

[dependencies]
jsonpath_rs = { git = "https://github.com/RedisJSON/jsonpath_rs.git", branch = "master" }

Usage example:

extern crate jsonpath_rs
#[macro_use] extern crate serde_json;

fn main() {
    let query = jsonpath_rs::compile("$..friends[0]");
    let path = jsonpath_rs::create(&query)

    let json_obj = json!({
        "school": {
            "friends": [
                {"name": "foo1", "age": 20},
                {"name": "foo2", "age": 20}
            ]
        },
        "friends": [
            {"name": "foo3", "age": 30},
            {"name": "foo4"}
        ]
    });

    let json = path.calc(&json_obj);

    assert_eq!(json, vec![
        &json!({"name": "foo3", "age": 30}),
        &json!({"name": "foo1", "age": 20})
    ]);
}
