helpers4 — Rust

General-purpose Rust helpers: one crate, one module per category (string, array, …), each behind its own Cargo feature.

[dependencies]
helpers4 = "0"                                                        # every module
# or only what you use:
helpers4 = { version = "0", default-features = false, features = ["string"] }

use helpers4::string::capitalize;

assert_eq!(capitalize("hello"), "Hello");

Helper names can repeat across modules (array::compact, object::compact); always go through the module path.

Quality bar

• 100% coverage (lines, functions, regions), enforced in CI
• Unit tests, property-based tests (proptest), doctests, benchmarks (criterion) where relevant
• cargo-deny on licenses and advisories, clippy with warnings denied
• Zero third-party dependencies by default

Status

Pre-release (0.0.1). Sister project of helpers4/typescript. See the roadmap and CONTRIBUTING.md.
