Struct JsonPath 

pub struct JsonPath(/* private fields */);

A path into a JSON document.

Implementations

impl JsonPath

pub fn root() -> JsonPath

Create an empty (root) path.

pub fn new(segments: Vec<PathSegment>) -> JsonPath

Create a path from segments.

pub fn parse(path: &str) -> JsonPath

Parse a path from dot notation (e.g., “user.name” or “items.0.value”).

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

Get the segments.

pub fn is_root(&self) -> bool

Check if this is the root path.

pub fn parent(&self) -> Option<JsonPath>

Get the parent path.

pub fn last(&self) -> Option<&PathSegment>

Get the last segment.

pub fn push(&mut self, segment: PathSegment)

Append a segment.

pub fn child_key(&self, key: impl Into<String>) -> JsonPath

Create a child path with a key.

pub fn child_index(&self, index: usize) -> JsonPath

Create a child path with an index.

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonPath

fn deserialize<__D>( __deserializer: __D, ) -> Result<JsonPath, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for JsonPath

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

Formats the value using the given formatter.

impl Hash for JsonPath

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

where __H: Hasher,

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.

impl Serialize for JsonPath

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
