Implementations on Foreign Types

impl Remove for Value

fn remove(&mut self, json_pointer: &str) -> Result<Option<Value>>

Examples: Remove an element in a table

use serde_json::Value;
use json_value_remove::Remove;

let mut array1: Value = serde_json::from_str(r#"{"my_table":["a","b","c"]}"#).unwrap();
assert_eq!(Some(Value::String("a".to_string())), array1.remove("/my_table/0").unwrap());
assert_eq!(r#"{"my_table":["b","c"]}"#, array1.to_string());

Examples: Remove a field from an object

use serde_json::Value;
use json_value_remove::Remove;

let mut object1: Value = serde_json::from_str(r#"{"field1.0":{"field1.1":"value1.1","field1.2":"value1.2"},"field2.0":"value2.0"}"#).unwrap();
assert_eq!(Some(Value::String("value1.2".to_string())), object1.remove("/field1.0/field1.2").unwrap());
assert_eq!(r#"{"field1.0":{"field1.1":"value1.1"},"field2.0":"value2.0"}"#,object1.to_string());
