Trait ScreenerFieldExt 

pub trait ScreenerFieldExt: ScreenerField + Sized {
    // Provided methods
    fn gt(self, v: f64) -> QueryCondition<Self> { ... }
    fn lt(self, v: f64) -> QueryCondition<Self> { ... }
    fn gte(self, v: f64) -> QueryCondition<Self> { ... }
    fn lte(self, v: f64) -> QueryCondition<Self> { ... }
    fn eq_num(self, v: f64) -> QueryCondition<Self> { ... }
    fn between(self, min: f64, max: f64) -> QueryCondition<Self> { ... }
    fn eq_str(self, v: impl Into<String>) -> QueryCondition<Self> { ... }
}

Fluent condition-building methods on any ScreenerField type.

This blanket trait is automatically implemented for all types that implement ScreenerField, including EquityField and FundField.

Example

use finance_query::{EquityField, ScreenerFieldExt};

// Numeric comparisons
let cond = EquityField::PeRatio.between(10.0, 25.0);
let cond = EquityField::AvgDailyVol3M.gt(500_000.0);
let cond = EquityField::EsgScore.gte(50.0);

// String equality
let cond = EquityField::Region.eq_str("us");
let cond = EquityField::Exchange.eq_str("NMS");

Provided Methods

fn gt(self, v: f64) -> QueryCondition<Self>

Filter where this field is greater than v.

fn lt(self, v: f64) -> QueryCondition<Self>

Filter where this field is less than v.

fn gte(self, v: f64) -> QueryCondition<Self>

Filter where this field is greater than or equal to v.

fn lte(self, v: f64) -> QueryCondition<Self>

Filter where this field is less than or equal to v.

fn eq_num(self, v: f64) -> QueryCondition<Self>

Filter where this field equals the numeric value v.

fn between(self, min: f64, max: f64) -> QueryCondition<Self>

Filter where this field is between min and max (inclusive).

fn eq_str(self, v: impl Into<String>) -> QueryCondition<Self>

Filter where this field equals the string value v.

Use for categorical fields like Region, Sector, Industry, Exchange.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Blanket implementation: every ScreenerField automatically gets all the fluent condition-building methods from ScreenerFieldExt.
