Trait EvalIndicator 

pub trait EvalIndicator: Send + Sync {
    // Required methods
    fn update(&mut self, input: &BarInput<'_>) -> Option<f64>;
    fn fields(&self) -> Vec<(&'static str, f64)>;
    fn warmup(&self) -> usize;
}

A uniform, object-safe indicator the engine drives one bar at a time.

Required Methods

fn update(&mut self, input: &BarInput<'_>) -> Option<f64>

Feed one bar’s BarInput; returns the primary value, or None while warming up or when the required feed is absent.

fn fields(&self) -> Vec<(&'static str, f64)>

Named output fields of the most recent update (empty for single-output).

fn warmup(&self) -> usize

Number of bars required before the first value.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
