Trait BatchNanExt 

pub trait BatchNanExt: Indicator<Input = f64, Output = f64> {
    // Provided methods
    fn batch_nan(&mut self, inputs: &[f64]) -> Vec<f64> { ... }
    fn batch_fast(&mut self, inputs: &[f64]) -> Vec<f64> { ... }
}

Fast batch for scalar f64 -> f64 indicators.

The generic BatchExt::batch returns Vec<Option<f64>> — 16 bytes per element (no niche fits an arbitrary f64), which a caller wanting a dense f64 series then has to walk a second time to map warmup Nones to NaN. This skips both the wide intermediate and the second pass: one allocation, one pass, warmup encoded as NaN. Both methods allocate the result and fill it through Indicator::batch_nan_into / Indicator::batch_fast_into, so an indicator’s faster formulation reaches them too.

Provided Methods

fn batch_nan(&mut self, inputs: &[f64]) -> Vec<f64>

One f64 per input, warmup positions filled with NaN, bit-for-bit equal to replaying update.

fn batch_fast(&mut self, inputs: &[f64]) -> Vec<f64>

The opt-in fast batch (Indicator::batch_fast_into) into a fresh vector: within the indicator’s documented tolerance of batch_nan, deterministic across platforms.

Dyn Compatibility

This trait is dyn compatible.

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