> **Latest release:** `0.1.1` (April 25, 2026). See the [workspace release notes](../../docs/releases/0.1.1.md) for highlights and upgrade guidance.

## Overview

`sklears-utils` hosts shared utilities used across the sklears workspace—configuration helpers, logging, dataset helpers, validation routines, and developer ergonomics.

## Key Features

- **Configuration**: Environment-aware configuration loaders, feature flag combinators, and CLI helpers.
- **Validation**: Data shape checks, feature metadata, error context propagation, and safe casting utilities.
- **Parallel Helpers**: Rayon thread-pool orchestration, chunking strategies, and work-stealing helpers.
- **Testing Support**: Fixtures, golden data loaders, and deterministic RNG wrappers for reproducible tests.

## Usage

This crate is primarily consumed internally, but developers extending sklears can depend on it for consistent utilities.

```rust
use sklears_utils::validation::check_array;
use scirs2_core::ndarray::Array2;

let x: Array2<f64> = // load data
    Array2::zeros((64, 10));

check_array(&x)?.ensure_finite()?;
```

## Status

- Validated by 494 passing tests in `0.1.1` (Stable).
- Acts as shared infrastructure for dozens of crates.
- Additional helpers and refactors are tracked in this crate’s `TODO.md`.
