Variants

And(Vec<FilterNode>)

Or(Vec<FilterNode>)

Condition

Fields

column: String

op: CompareOp

value: SqlValue

ArrayIncludes

Array-level includes filter: “exists an element in the parallel arrays satisfying all conditions”. Compiles to arrayExists(lambda, arrays).

Fields

array_columns: Vec<String>

ClickHouse column names of the parallel arrays participating in the lambda.

element_conditions: Vec<Vec<FilterNode>>

Each inner Vec is one includes object (conditions AND-ed within). Multiple inner Vecs are AND-ed as separate arrayExists calls.

Empty

Implementations

impl FilterNode

pub fn is_empty(&self) -> bool
