Crate rsjson

Json file parser library

Installation

...
[dependencies]
rsjson = "0.6.0";

or run

cargo add rsjson

Importation

use rsjson;

Code example

• read and parse a json file

let json: Result<rsjson::Json, String> = rsjson::Json::fromFile("/path/to/file.json");

• read and parse a json structure from a string
• the string can be both “normal” and raw

let json: Result<rsjson::Json, String> = rsjson::json!(
    r#"{
        "key" : "value",
        "second_key" : ["one", "two"]
    }"#
);

• in both previous cases, remeber to handle the eventual error (e.g. using match) or to call unwrap()

• create an empty json instance

let json = rsjson::Json::new();

• add a node

json.addNode(
    rsjson::Node::new(
        "nodeLabel",
        rsjson::NodeContent::Int(32)
    )
);

• edit a node’s content

json.setContent(
    "nodeLabel",
    rsjson::NodeContent::Bool(true)
);

• remove a node

json.remove(
    "nodeLabel"
);

• check the existance of a label

let exists: bool = json.has("nodeLabel");
