Trait StackSamples 

pub trait StackSamples: Sized {
    type Batch;

    // Required method
    fn stack_samples(samples: Vec<Self>) -> Result<Self::Batch, DataError>;
}

サンプル列（Vec<Self>）を 1 バッチへ積み上げる型（IterableBatches が使う）。

pub である理由: 公開 impl Iterator for IterableBatches の where 節に現れるため、pub(crate) にすると private_bounds lint （-D warnings）に抵触する。実装は Tensor<T> と 2／3 要素タプルのみ。

Required Associated Types

type Batch

積み上げ後のバッチ型。

Required Methods

fn stack_samples(samples: Vec<Self>) -> Result<Self::Batch, DataError>

samples を先頭軸へ積む。空は DataError::EmptyBatch。

Dyn Compatibility

This trait is not dyn compatible.

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