RustUse/use-math

Utility-first Rust math crates with concrete focused APIs across the entire workspace.
Focused crates stay small. The facade crate composes them behind opt-in features and exposes matching nested modules for explicit crate-shaped namespacing.

This repository is the source workspace for RustUse's math surface. Today it combines concrete focused crates for arithmetic helpers, modular arithmetic, prime utilities, polynomial primitives, equation helpers, structural eigenvalue primitives, approximate numerical helpers, vector primitives, matrix primitives, interval primitives, checked combinatorics, Catalan-family sequences, Collatz trajectory exploration, Geode-array primitives, progression helpers, finite algebra law helpers, integer helpers, boolean algebra helpers, small set helpers, explicit trigonometry helpers, descriptive statistics helpers, solver-style linear helpers, raw-number helpers, complex numbers, numerical calculus, probability, real-number helpers, and rational arithmetic. use-math composes the workspace behind feature flags while keeping root re-exports aligned with the concrete APIs each focused crate exposes. Geometry now lives in the sibling use-geometry repository and is no longer re-exported by the use-math facade.

Current status

• The crates.io release line is live.
• Use published crates for released versions, or pin a Git revision when you need unreleased workspace changes.
• use-arithmetic, use-modular, use-prime, use-polynomial, use-equation, use-eigen, use-numerical, use-vector, use-matrix, use-combinatorics, use-catalan, use-collatz, use-geode, use-series, use-algebra, use-integer, use-logic, use-set, use-trigonometry, use-statistics, use-linear, use-number, use-complex, use-calculus, use-probability, use-real, use-interval, and use-rational are the concrete focused APIs in this workspace today.
• Geometry moved to the sibling use-geometry repository and is no longer part of the use-math workspace or facade.
• Future lockstep releases still publish focused crates first in dependency order, including use-polynomial before use-equation, use-interval before use-numerical and use-real, use-vector before use-matrix, use-matrix before use-linear, and use-math after crates.io index propagation.

Tip

Prefer the focused crates when you want the narrowest dependency footprint. Choose use-math when consumer ergonomics and one-dependency integration matter more than shaving every unused surface.

Choose your entry point

Pick the crate based on the integration shape you want, not just the total feature count.

Installation

This repository is public before the first crates.io publish. Until the first release wave is live, use the workspace directly or depend on a Git revision. The versioned snippets below apply after the published release line exists on crates.io.

Git dependency before the first crates.io release:

[dependencies]
use-math = { git = "https://github.com/RustUse/use-math", rev = "<commit>" }

For focused crates, replace use-math with the focused crate you need, such as use-combinatorics, use-collatz, or another focused crate like use-algebra. Pin a commit or future tag instead of following the moving default branch. For geometry primitives, use the sibling use-geometry repository.

When consuming the published release line, pull in the smallest surface that matches your application.

Facade crate with default features:

[dependencies]
use-math = "0.0.7"

Facade crate with combinatorics only:

[dependencies]
use-math = { version = "0.0.7", default-features = false, features = ["combinatorics"] }

Focused crates directly:

[dependencies]
use-combinatorics = "0.0.6"
use-collatz = "0.0.6"
use-modular = "0.0.6"
use-prime = "0.0.6"
use-polynomial = "0.0.6"
use-equation = "0.0.6"
use-eigen = "0.0.6"
use-numerical = "0.0.6"

Note

The workspace is still pre-1.0. Release sequencing matters because the use-math facade depends on matching focused-crate versions.

Quick examples

Geometry examples now live in the sibling use-geometry repository. use-math no longer re-exports geometry types or a geometry feature.

Checked counting through the facade

use use_math::prelude::*;

assert_eq!(factorial(5)?, 120);
assert_eq!(permutations(5, 3)?, 60);
assert_eq!(combinations(5, 2)?, 10);
# Ok::<(), use_math::combinatorics::CombinatoricsError>(())

Validated input path

Use try_new constructor variants when coordinates or shapes originate outside your codebase, such as user input, configuration files, or network payloads. Infallible constructors like Point2::new(...) or Aabb2::from_points(...) remain available for values you already trust.

Important

Keep validation at the edge. Once data is trusted, the APIs stay lightweight and composable.

Feature model

The facade crate exposes a small feature surface:

Feature	Enables	Default
arithmetic	Re-exports from use-arithmetic, including checked and overflow-mode arithmetic helpers, floor-division helpers, and the nested use_math::arithmetic module	No

If you want the facade but only one module, disable defaults and enable the feature you need:

[dependencies]
use-math = { version = "0.0.7", default-features = false, features = ["combinatorics"] }

Maturity and release model

RustUse/use-math is intentionally pre-1.0. The current release line is 0.0.x, and the facade crate should publish only after the focused crates for that same version are available to the registry index.

Release concern	Current posture
Versioning	Lockstep 0.0.x releases across the workspace
Publish order	Publish focused crates first, then publish use-math
API growth	Favor small, composable surfaces over rapid expansion
Dependency policy	Keep dependencies minimal and predictable

Development

Run commands from the repository root.

Requirements:

Rust 1.95.0 or newer
cargo

Repo-owned DX shortcuts:

cargo xcheck
cargo xlint
cargo xtest
cargo xtest-minimal
cargo xexamples
cargo xdoc

These aliases live in .cargo/config.toml, so contributors do not need make for the common workspace validation path. If you are using VS Code, the same flows are available through the checked-in tasks in .vscode/tasks.json, and the repository recommends the Rust, TOML, YAML, and GitHub Actions extensions it expects through .vscode/extensions.json.

Open-source intake and onboarding:

• GitHub issue forms now cover bugs, feature requests, and docs/onboarding gaps.
• The issue chooser routes questions and design exploration toward Discussions once the repository enables them.
• The pull request template now asks for linked issue or discussion context, change type, and the repo-owned Cargo alias checks.

Optional maintainer and contributor tooling bootstrap:

bash scripts/bootstrap-dev-tools.sh
pwsh -File scripts/bootstrap-dev-tools.ps1

Both scripts install the optional Cargo tools used across local advisory, release, and supply-chain workflows: cargo-deny, cargo-audit, cargo-cyclonedx, release-plz, and cargo-machete.

If you are preparing a clean-history open-source launch, use docs/first-public-commit.md as the checklist for the first public revision and the first public push, and use docs/history-reset-and-republish.md as the exact operator runbook for rewriting history in the existing private repository.

If you prefer a containerized setup, the repository also ships a checked-in devcontainer in .devcontainer/ with the Rust toolchain, recommended VS Code extensions, and an initial cargo xcheck post-create validation.

Primary validation commands:

cargo fmt --all --check
cargo check --workspace --all-features
cargo check --workspace --all-features --examples
cargo test --workspace --all-features
cargo test --workspace --no-default-features
cargo clippy --workspace --all-targets --all-features -- -D warnings
cargo doc --workspace --all-features --no-deps
cargo deny check
cargo audit

Convenience targets for the release path:

make help
make verify
make examples
make test-minimal
make publish-dry-run-focused
make release-readiness

make release-readiness intentionally validates the focused crates' publish surface first. The use-math facade still needs its final cargo publish --dry-run only after matching focused-crate versions exist in the crates.io index.

If you prefer not to use make, the Cargo aliases and VS Code tasks cover the same day-to-day validation flows cross-platform.

Cargo.lock is committed intentionally for reproducible CI, advisory checks, and release dry runs in this library workspace.

Mirrors

The canonical repository is hosted on GitHub. Additional mirrors can be activated for redundancy and contributor access once their repository variables and SSH key material are configured.

See FORGES.md for the cross-forge sync model and mirror activation details.

Contributing

Contributions should favor correctness, clear naming, small APIs, and minimal dependencies over broad surface area. See CONTRIBUTING.md for validation, release, and cross-forge expectations.

Community and project policy

• Use the RustUse support guidance for help and routing.
• Use the RustUse security policy for private vulnerability reporting.
• Use the RustUse code of conduct for collaboration expectations.
• Use GOVERNANCE.md and MAINTAINERS.md for decision-making and release authority.
