Crates.io Documentation License Minimum Rust Version

Latest release: 0.2.0 (July 14, 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 loading (Config::load_environment), hot-reloadable config files, and validation.
  • Validation: Data shape checks, feature metadata, error context propagation, and safe casting utilities.
  • Parallel Helpers: Custom ThreadPool/WorkStealingQueue primitives plus chunked ParallelIterator/ParallelReducer helpers.
  • Testing Support: Synthetic dataset generators (make_classification, make_regression, make_blobs, ...) and deterministic RNG wrappers (seeded get_rng) 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_2d;
use scirs2_core::ndarray::Array2;

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

check_array_2d(&x)?;

Status

  • Validated by 494 passing tests in 0.2.0 (Stable).
  • Acts as shared infrastructure for dozens of crates.
  • Additional helpers and refactors are tracked in this crate’s TODO.md.
