10 (1) You can create a `JsonValue` instance by:
15 use ylong_json::JsonValue;
18     // You can use `from_str` to try to generate a `JsonValue` instance from 
22     let json_value = JsonValue::from_str(str);
25     // You can use `from_text` to generate a `JsonValue` instance from 
29     let json_value = JsonValue::from_text(text);
33     // try to generate a `JsonValue` instance.
36     let json_value = JsonValue::from_file(path);
40     // that implements io::Read and try to generate a `JsonValue` instance.
43     let json_value = JsonValue::from_reader(&mut reader);

89 use ylong_json::JsonValue;
100     // Creates a JsonValue instance from the example string, the syntax is 
102     let json_value = JsonValue::from_str(JSON_TEXT).unwrap();
106     let value: &JsonValue = &json_value["key"];
110     let array_item: &JsonValue = &json_value["array"][0];
113     // `&JsonValue::Null` will be returned.
114     let no_such_key: &JsonValue = &json_value["no_such_key"];
117     // `&JsonValue::Null` will also be returned.
118     let no_such_index: &JsonValue = &json_value["array"][100];
120     // If you use a subscript to visit `JsonValue` types other than Object and Array, 
121     // `&JsonValue::Null` will also be returned.
122     let invalid_index: &JsonValue = &json_value["key"]["invalid"];
123     let invalid_index: &JsonValue = &json_value["key"][0];
126 You can also use the same method to obtain a mutable reference to `JsonValue`. 
129 use ylong_json::JsonValue;
140     // Creates a JsonValue instance from the example string, the syntax is
143     let mut json_value = JsonValue::from_str(JSON_TEXT).unwrap();
146     // In the libraty, many primitive types implement conversion from themselves to JsonValue, 
147     // so they can be converted to `JsonValue` by using `into()` method.
165     // then the key will be inserted in the table with the corresponding value JsonValue::Null,
178     // subscript exceeds the Array length, then a `JsonValue::Null` will be added at
