Struct jsonpath_rust::JsonPathFinder

pub struct JsonPathFinder { /* private fields */ }

The base structure stitching the json instance and jsonpath instance

Implementations

impl JsonPathFinder

pub fn new(json: Box<Value>, path: Box<JsonPathInst>) -> Self

creates a new instance of JsonPathFinder

pub fn new_with_cfg( json: Box<Value>, path: Box<JsonPathInst>, cfg: JsonPathConfig ) -> Self

pub fn set_cfg(&mut self, cfg: JsonPathConfig)

sets a cfg with a new one

pub fn set_path(&mut self, path: Box<JsonPathInst>)

updates a path with a new one

pub fn set_json(&mut self, json: Box<Value>)

updates a json with a new one

pub fn set_json_str(&mut self, json: &str) -> Result<(), String>

updates a json from string and therefore can be some parsing errors

pub fn set_path_str(&mut self, path: &str) -> Result<(), String>

updates a path from string and therefore can be some parsing errors

pub fn from_str(json: &str, path: &str) -> Result<Self, String>

create a new instance from string and therefore can be some parsing errors

pub fn from_str_with_cfg( json: &str, path: &str, cfg: JsonPathConfig ) -> Result<Self, String>

pub fn instance(&self) -> PathInstance<'_>

creates an instance to find a json slice from the json

pub fn find_slice(&self) -> Vec<JsonPathValue<'_, Value>>

finds a slice of data in the set json. The result is a vector of references to the incoming structure.

pub fn find(&self) -> Value

finds a slice of data and wrap it with Value::Array by cloning the data. Returns either an array of elements or Json::Null if the match is incorrect.

pub fn find_as_path(&self) -> Value

finds a path of the values. If the values has been obtained by moving the data out of the initial json the path is absent.

Trait Implementations

impl Debug for JsonPathFinder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
