A Nix library for building Rust projects with minimal configuration, leveraging Nix's sandboxing and caching.
Naersk is a Nix library designed to build Rust projects seamlessly within the Nix ecosystem. It automates dependency resolution and compilation by parsing Cargo.lock, turning Rust code into Nix derivations. This solves the problem of integrating Rust builds into Nix-based workflows without manual configuration or external tools.
Rust developers using Nix for development, packaging, or deployment, especially those in NixOS or Nix-driven CI/CD environments.
Developers choose Naersk for its minimal setup, reproducibility, and efficient caching. It uniquely avoids IFD, works in sandboxed environments, and integrates Rust's tooling with Nix's declarative and isolated build system.
Build Rust projects in Nix - no configuration, no code generation, no IFD, sandbox friendly.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Builds Rust projects by simply pointing to source code with Cargo.toml and Cargo.lock, requiring minimal Nix code as shown in the basic usage example.
Leverages Nix's sandboxing for isolated builds, ensuring security and consistency across environments without extra configuration.
Parses Cargo.lock in pure Nix code, making it compatible with Hydra and sandboxed builds, as highlighted in the introduction.
Uses a two-step derivation process to cache dependencies, avoiding rebuilds for unchanged code and improving build times.
Integrating custom Rust versions requires manual overlays and sha256 hash management, as detailed in the README, which is error-prone and tedious.
The incremental build mechanism breaks if overrideAttrs is misused, forcing users to pass parameters directly or disable singleStep, adding complexity.
Adds significant overhead for teams not using Nix, limiting adoption outside the Nix community and requiring prior Nix knowledge.
