pub struct QueryCondition {
    pub operator: Operator,
    pub operands: Vec<QueryValue>,
}

A single filter condition

Fields

operator: Operator

The comparison operator

operands: Vec<QueryValue>

The operands: [field_name, value(s)…]

Implementations

impl QueryCondition

pub fn new(field: impl Into<String>, operator: Operator) -> Self

Arguments

• field - The field to filter on (e.g., “region”, “avgdailyvol3m”)
• operator - The comparison operator (Eq, Gt, Lt, etc.)

pub fn value<T: Into<f64>>(self, value: T) -> Self

Set a numeric value for the condition

pub fn value_str(self, value: impl Into<String>) -> Self

Set a string value for the condition

pub fn between<T: Into<f64>>(self, min: T, max: T) -> Self

Set two values for a BETWEEN condition
