Variants

Arrow

-> keeps the value as json

LongArrow

->> keeps the value as text or int.

HashArrow

Question

? Checks whether text key exist as top-level key or array element.

QuestionOr

?| Checks whether any of the text keys exist as top-level keys or array elements.

QuestionAnd

?& Checks whether all of the text keys exist as top-level keys or array elements.

AtArrow

@> Checks whether left json contains the right json

ArrowAt

<@ Checks whether right json contains the left json

AtQuestion

@? Checks whether JSON path return any item for the specified JSON value

AtAt

@@ Returns the result of a JSON path predicate check for the specified JSON value.

HashMinus

#- Deletes the field or array element at the specified keypath.

Implementations

impl JsonOperator

pub fn to_func_name(&self) -> String

Trait Implementations

impl Clone for JsonOperator

fn clone(&self) -> JsonOperator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JsonOperator

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

Formats the value using the given formatter.

impl Display for JsonOperator

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

Formats the value using the given formatter.

impl Drive for JsonOperator

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for JsonOperator

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl PartialEq for JsonOperator

fn eq(&self, other: &JsonOperator) -> 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.
