Enum FilterExpression

        left: FilterOperand,
        operator: ComparisonOperator,
        right: FilterOperand,
    },
    Logical {

}

Represents different types of filter expressions. Supports comparisons, logical operations, negation, and function calls.

Variants

Comparison

Comparison operations (==, !=, <, >, <=, >=)

Fields

left: FilterOperand

operator: ComparisonOperator

right: FilterOperand

Logical

Logical operations (&&, ||)

Fields

left: Box<FilterExpression>

operator: LogicalOperator

right: Box<FilterExpression>

Not(Box<FilterExpression>)

Unary negation (!)

Function

Function calls (CONTAINS, STARTS_WITH, etc.)

Fields

func: FilterFunction

args: Vec<FilterOperand>

Trait Implementations

impl Clone for FilterExpression

fn clone(&self) -> FilterExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FilterExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FilterExpression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for FilterExpression

impl StructuralPartialEq for FilterExpression
