Create a set operation.

pub fn insert( column: impl Into<String>, path: impl Into<String>, value: impl Into<JsonValue>, ) -> Self

Create an insert operation.

pub fn remove(column: impl Into<String>, path: impl Into<String>) -> Self

Create a remove operation.

pub fn array_append( column: impl Into<String>, path: impl Into<String>, value: impl Into<JsonValue>, ) -> Self

Create an array append operation.

pub fn merge(column: impl Into<String>, value: impl Into<JsonValue>) -> Self

Create a merge operation.

pub fn increment( column: impl Into<String>, path: impl Into<String>, amount: f64, ) -> Self

Create an increment operation.

pub fn to_postgres_expr(&self) -> (String, Vec<FilterValue>)

Generate PostgreSQL SQL expression.

pub fn to_mysql_expr(&self) -> (String, Vec<FilterValue>)

Trait Implementations

impl Clone for JsonOp

fn clone(&self) -> JsonOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for JsonOp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JsonOp

fn eq(&self, other: &JsonOp) -> 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 JsonOp

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
