nw-fp-rust SKILL.md skillA
nw-fp-rust from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-fp-rust@git:20261102.c67d57bPins git:20261102.c67d57b in mdr.lock. Pin the fingerprint instead.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FP in Rust -- Functional Software Crafter Skill Cross-references: [fp-principles](../nw-fp-principles/SKILL.md) | [fp-domain-modeling](../nw-fp-domain-modeling/SKILL.md) | [pbt-rust](../nw-pbt-rust/SKILL.md) ## When to Choose Rust - Best for: making illegal states unrepresentable at the TYPE level, with the compiler enforcing it | systems where a wrong state must be a compile error, not a runtime one | performance-critical domain cores - Not ideal for: teams needing the fastest possible prototyping loop | domains where the borrow checker's learning cost outweighs the safety gain (short-lived scripts, throwaway tooling) ## [STARTER] Quick Setup ```bash cargo new order_service && cd order_service # Add proptest or quickcheck as a dev-dependency for property-based testing cargo build && cargo test ``` **Test runner**: `cargo test`. Add `proptest = "1"` (or `quickcheck`) under `[dev-dependencies]`. ## [STARTER] Type System for Domain Modeling Rust's `enum` is a REAL algebraic sum type with payload per variant, and the compiler REFUSES to compile a `match` that omits a case -- this is not a lint, it is a hard error. No other mainstream systems language makes …

How to install
mdr add nwave-ai/nwave/nw-fp-rust@sha256:4cc1f331adac6e8eThe line at the top of this page pins the label git:20261102.c67d57b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
