It is native-addon of jsonpath_lib that is 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.
