JsonOperator

Variants

Arrow

-> keeps the value as json

LongArrow

->> keeps the value as text or int.

HashArrow

#> Extracts JSON sub-object at the specified path

HashLongArrow

#>> Extracts JSON sub-object at the specified path as text

Colon

: Colon is used by Snowflake (Which is similar to LongArrow)

AtArrow

jsonb @> jsonb -> boolean: Test whether left json contains the right json

ArrowAt

jsonb <@ jsonb -> boolean: Test whether right json contains the left json

HashMinus

jsonb #- text[] -> jsonb: Deletes the field or array element at the specified path, where path elements can be either field keys or array indexes.

AtQuestion

jsonb @? jsonpath -> boolean: Does JSON path return any item for the specified JSON value?

AtAt

jsonb @@ jsonpath → boolean: Returns the result of a JSON path predicate check for the specified JSON value. Only the first item of the result is taken into account. If the result is not Boolean, then NULL is returned.

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<(), Error>

Formats the value using the given formatter.

impl Display for JsonOperator

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

Formats the value using the given formatter.

impl Hash for JsonOperator

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 Ord for JsonOperator

fn cmp(&self, other: &JsonOperator) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for JsonOperator

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

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

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.

impl PartialOrd for JsonOperator

fn partial_cmp(&self, other: &JsonOperator) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Visit for JsonOperator

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

impl VisitMut for JsonOperator

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,
