Especially json parsing and jsonpath parsing can take significant time, +compared to a simple find. + +The methods `find`, `find_as_path`, `find_slice` and `find_slice_ptr` take the same inputs, but handle them differently +depending on your usecase.

Especially json parsing and jsonpath parsing can take significant time, -compared to a simple find. - -The methods `find`, `find_as_path`, `find_slice` and `find_slice_ptr` take the same inputs, but handle them differently -depending on your usecase. They are further described in -the [docs](https://docs.rs/jsonpath-rust/latest/jsonpath_rust/enum.JsonPath.html#implementations). - -```rust -use jsonpath_rust::{JsonPath, JsonPathValue}; -use serde_json::json; -use std::str::FromStr; - -fn main() { - let data = json!({"first":{"second":[{"active":1},{"passive":1}]}}); - let path = JsonPath::from_str("$.first.second[?(@.active)]").unwrap(); - let slice_of_data = path.find_slice(&data); - - let expected_value = json!({"active":1}); - let expected_path = "$.['first'].['second'][0]".to_string(); - - assert_eq!( - slice_of_data, - vec![JsonPathValue::Slice(&expected_value, expected_path)] - ); -} +## Usage +Run the main.rs. +It will print the test results in the console with the following format: ``` +... +Skipping test case: `` because of reason: `reason` +... +Failed tests: -### The structure -

-### JsonLike - -The library provides a trait `JsonLike` that can be implemented for any type. -This allows you to use the `JsonPath` methods on your own types. - -### Update the JsonLike structure by path +------- ------- + -The library does not provide the functionality to update the json structure in the query itself. -Instead, the library provides the ability to update the json structure by the path. -Thus, the user needs to find a path for the `JsonLike` structure and update it manually. +... -There are two methods in the `JsonLike` trait: +RFC9535 Compliance tests: +Total: 671 +Passed: 209 +Failed: 462 -- `reference_mut` - returns a mutable reference to the element by the path -- `reference` - returns a reference to the element by the path - They accept a `JsonPath` instance and return a `Option<&mut Value>` or `Option<&Value>` respectively. - The path is supported with the limited elements namely only the elements with the direct access: -- root -- field -- index - The path can be obtained manually or `find_as_path` method can be used. - -```rust -#[test] -fn update_by_path_test() -> Result<(), JsonPathParserError> { -
