Struct JsonPath 

pub struct JsonPath { /* private fields */ }

A parsed JSONPath.

Implementations

impl JsonPath

pub fn parse(path: &str) -> Result<Self, PathError>

Parse a path that must start with $.

pub fn is_definite(&self) -> bool

True when the path can yield at most one value.

pub fn reference_steps(&self) -> Option<Vec<Step>>

For a definite (reference) path, the chain of property names and indexes it walks. None for an indefinite path.

pub fn normalized(&self) -> String

Jayway-style normalized rendering, used in error messages.

pub fn evaluate(&self, root: &Value) -> Result<Value, PathError>

Evaluate against root. Definite paths return the single match or PathError::NoResults; indefinite paths return an array of matches.
