[](../../LICENSE)
[](https://www.rust-lang.org)
> **Latest release:** `0.1.0-beta.1` (January 1, 2026). See the [workspace release notes](../../docs/releases/0.1.0-beta.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 indirectly by the entire workspace test suite (11,292 passing tests) in `0.1.0-beta.1`.
- Acts as shared infrastructure for dozens of crates.
- Additional helpers and refactors are tracked in this crate’s `TODO.md`.
