Struct jsonpath_plus::JsonPath

pub struct JsonPath { /* private fields */ }

A compiled JSON path. Can be used to match against items any number of times, preventing recompilation of the same pattern many times.

Implementations

impl JsonPath

pub fn compile(pattern: &str) -> Result<JsonPath, ParseError>

Compile a JSON path, which can be used to match items multiple times.

Errors

• If the provided pattern fails to parse as a valid JSON path

pub fn find<'a>(&self, value: &'a Value) -> Vec<&'a Value>

Find this pattern in the provided JSON value

pub fn delete(&self, value: &Value) -> Value

Delete all items matched by this pattern on the provided JSON value, and return the resulting object

pub fn replace(&self, value: &Value, f: impl FnMut(&Value) -> Value) -> Value

Replace items matched by this pattern on the provided JSON value, filling them with the value returned by the provided function, then return the resulting object

pub fn find_str(&self, str: &str) -> Result<Vec<Value>, Error>

Find this pattern in the provided JSON string

Errors

• If the provided value fails to deserialize

pub fn delete_str(&self, str: &str) -> Result<Value, Error>

Delete items matching this pattern in the provided JSON string

Errors

• If the provided value fails to deserialize

pub fn replace_str(
    &self,
    str: &str,
    f: impl FnMut(&Value) -> Value
) -> Result<Value, Error>
