## What it is
Naersk is a Nix library for building Rust projects by turning Cargo projects into Nix derivations. It parses Cargo.lock, fetches dependencies, and compiles inside Nix's sandbox without IFD or code generation.

## Use cases
- build rust projects with nix
- package a cargo application as a nix derivation
- reproducible rust builds with cargo.lock
- use rust in nixos system packages
- build rust with hydra without import-from-derivation

## When to choose
- you want zero-config Nix builds for Rust projects
- you need sandbox-friendly, cached dependency builds
- you use Hydra or Nix flakes and want to avoid IFD

## When to avoid
- you don't use the Nix package manager
- you need fine-grained control over cargo features or workspace overrides that naersk doesn't expose
- you prefer crane or buildRustPackage from nixpkgs

## Facets
- artifact type: library
- maturity: active
- function: build-tool, package-manager, developer-tools
- domain: developer-tools, programming-languages
- platform: cli, cross-platform
- tags: nix, rust, cargo, reproducible-builds, flakes, devops, linux, macos
