Installation

[dependencies]
json_value_search = "0.1"

Usage

extern crate json_value_search;

use json_value_search::Search;
use serde_json::Value;

let value: Value = serde_json::from_str(r#"{"field_A":[{"field.B":"value_B"},{"field_C":"value_C"}]}"#).unwrap();

let value_expected_with_wildcard: Value = serde_json::from_str(r#"[{"field.B":"value_B"},{"field_C":"value_C"}]"#).unwrap();
assert_eq!(Some(value_expected_with_wildcard),value.clone().search(r#"/field_A/*"#));

let value_expected_for_specific_field: Value = serde_json::from_str(r#"["value_B"]"#).unwrap();
assert_eq!(Some(value_expected_for_specific_field),value.clone().search(r#"/field_A/*/field.B"#));

let value_expected_for_specific_index: Value = serde_json::from_str(r#"{"field.B":"value_B"}"#).unwrap();
assert_eq!(Some(value_expected_for_specific_index),value.clone().search(r#"/field_A/0"#));

let value_expected_with_regex: Value = serde_json::from_str(r#"["value_B","value_C"]"#).unwrap();
assert_eq!(Some(value_expected_with_regex),value.clone().search(r#"/field_A/*/field.+"#));
