sklears-utils

Latest release: 0.1.0-beta.1 (January 1, 2026). See the workspace release notes 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.

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.
