Crate plainjson[−][src]
Expand description
This library simply provides:
- JsonTag: A low-level JSON tag parser which reads JSON tags from an instance which implements trait std::io::Read
- JsonNode: A JSON parser which supports getting or setting value from/to selected JSON nodes by JSONPath
Note: Filter expression in JSONPath is not implemented yet, so currently filter expression is not supported.
Getting value by JSONPath is like:
use plainjson::JsonNode; fn get_value_by_json_path() { let json = r#"{"a": 123, "b": {"c": "hello"}}"#; let mut json = JsonNode::parse_single_node(json.as_bytes()).unwrap(); let c = json.get_str("$.b.c").unwrap(); assert_eq!(c, Some(String::from("hello"))); }
Setting value by JSONPath is like:
use plainjson::JsonNode; fn set_value_by_json_path() { let json = r#"{"a": 123, "b": [3, 2, 1]}"#; let mut json = JsonNode::parse_single_node(json.as_bytes()).unwrap(); json.set_bool("$.b[1]", true).unwrap(); assert_eq!(json.to_string(), r#"{"a": 123, "b": [3, true, 1]}"#) }
If you need to access low-level JSON tags, use JsonTag:
use plainjson::JsonTag; fn fix_json() { let json = r#"{"a": test, "b": "world"}"#; let mut tags = JsonTag::parse(json.as_bytes()).unwrap(); tags[3] = JsonTag::Literal(String::from(r#""test""#)); assert_eq!(JsonTag::to_string(&tags), r#"{"a": "test", "b": "world"}"#); }
