Struct AugmentationPipeline 

pub struct AugmentationPipeline {
    pub steps: Vec<AugmentationStep>,
    pub rng_seed: u64,
}

A composable, ordered sequence of augmentation steps.

Steps are applied left-to-right. Each step receives its own AugRng derived from the pipeline seed advanced by the step index so results are deterministic given the same seed.

Fields

steps: Vec<AugmentationStep>

The ordered list of augmentation steps.

rng_seed: u64

Seed used to derive per-step RNG states.

Implementations

impl AugmentationPipeline

pub fn new(seed: u64) -> Self

Create an empty pipeline with the given RNG seed.

pub fn add_step(self, step: AugmentationStep) -> Self

Append a step and return self (builder pattern).

pub fn apply( &self, input: &ArrayD<f64>, training: bool, ) -> Result<ArrayD<f64>, AugmentationError>

Apply all steps to input sequentially.

A fresh AugRng is derived for each step from rng_seed ^ (step_index * prime), guaranteeing reproducibility while avoiding correlation between steps.

pub fn num_steps(&self) -> usize

Number of steps in the pipeline.
