Struct JsonPath 

pub struct JsonPath { /* private fields */ }

A compiled JSONPath expression.

Implementations

impl JsonPath

pub fn builder() -> JsonPathBuilder

Returns a typed JSONPath builder.

pub fn from_segments(segments: impl Into<Vec<Segment>>) -> Self

Builds a path from already typed segments.

pub fn segments(&self) -> &[Segment]

Path segments after the root $.

pub fn is_singular(&self) -> bool

Whether this path only contains exact member and index selectors.

pub fn matches_path(&self, path: &[PathElement]) -> bool

Returns whether this JSONPath matches an already tracked value path.

pub fn match_count(&self, path: &[PathElement]) -> usize

Returns how many ways this JSONPath matches an already tracked value path.

RFC 9535 selector lists preserve duplicate selections, so overlapping union members can match the same concrete path more than once.

Trait Implementations

impl Clone for JsonPath

fn clone(&self) -> JsonPath

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonPath

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

Formats the value using the given formatter.

impl Display for JsonPath

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

Formats the value using the given formatter.

impl Eq for JsonPath

impl FromStr for JsonPath

type Err = JsonError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for JsonPath

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for JsonPath

fn eq(&self, other: &JsonPath) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
