Expand description

Linked list structure of a JSONPath query.

Variants§

§

Root(Option<Box<JsonPathQueryNode>>)

The first link in the list representing the root ‘$’ character.

§

Child(Label, Option<Box<JsonPathQueryNode>>)

Represents direct descendant with a label (‘.’ token).

§

AnyChild(Option<Box<JsonPathQueryNode>>)

Represents direct descendant with a wildcard (‘.*’ tokens).

§

Descendant(Label, Option<Box<JsonPathQueryNode>>)

Represents recursive descent (‘..’ token).

Implementations§

source§

impl JsonPathQueryNode

source

pub fn child(&self) -> Option<&Self>

Retrieve the child of the node or None if it is the last one on the list.

source

pub fn iter(&self) -> JsonPathQueryIterator<'_>

Create an iterator over nodes of the query in sequence, starting from the root.

impl PartialEq<JsonPathQueryNode> for JsonPathQueryNode

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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