# jsonpath-rs
[![Build Status](https://travis-ci.org/freestrings/jsonpath.svg?branch=master)](https://travis-ci.org/freestrings/jsonpath)
It is native-addon of [jsonpath_lib](https://github.com/freestrings/jsonpath) that is [JsonPath](https://goessner.net/articles/JsonPath/) engine written in Rust.
## Notice
Pre-built 바이너리는 제공하진 않고 소스를 컴파일해서 설치한다. 만약 Rust가 설치되지 않았다면 자동으로 설치된다.
Build from source instead of using pre-built binary, and if Rust is not installed, the latest version is automatically installed.
> Not yet tested in Windows.
> Supported node version is under v12.0.
