Struct QueryCondition 

pub struct QueryCondition<F: ScreenerField> {
    pub field: F,
    pub operator: Operator,
    pub value: ConditionValue,
}

A typed filter condition for a screener query.

Created via ScreenerFieldExt methods on a field enum variant. The custom Serialize impl produces the exact format Yahoo Finance expects: {"operator": "gt", "operands": ["fieldname", value]}.

Example

use finance_query::{EquityField, ScreenerFieldExt};

let volume_filter = EquityField::AvgDailyVol3M.gt(200_000.0);
let region_filter = EquityField::Region.eq_str("us");
let pe_filter     = EquityField::PeRatio.between(10.0, 25.0);

Fields

field: F

The field to filter on.

operator: Operator

The comparison operator.

value: ConditionValue

The filter value(s).
