Struct Filter 

pub struct Filter {
    pub left: String,
    pub operation: FilterOperator,
    pub values: Vec<Value>,
}

One scanner filter clause (left / operation / right).

Fields

left: String

Column key on the left side of the comparison.

operation: FilterOperator

Operator applied to left vs values.

values: Vec<Value>

Right-hand side value(s); field-to-field compares use column name strings.

Implementations

impl Filter

pub fn new( left: impl Into<String>, operation: FilterOperator, values: impl IntoIterator<Item = Value>, ) -> Self

Builds a filter from one or many right-hand values.

pub fn on_extra( extra: ExtraFilter, operation: FilterOperator, values: impl IntoIterator<Item = Value>, ) -> Self

Builds a filter on an ExtraFilter left key.

pub fn to_json(&self) -> Value

Serializes to one { "left", "operation", "right" } object for the scan payload.
