A Heroku buildpack for Rust applications with support for Rustup, Cargo, and build caching.
Heroku buildpack for Rust is a deployment tool that allows Rust applications to run on the Heroku platform. It integrates with Rust's toolchain, including Cargo and Rustup, to compile and deploy Rust projects efficiently. It solves the problem of deploying Rust applications to a managed cloud environment with minimal configuration.
Rust developers who want to deploy their applications to Heroku without managing infrastructure. It's also useful for teams building polyglot applications that combine Rust with other languages on Heroku.
Developers choose this buildpack for its robust caching, automatic toolchain management, and flexibility in customizing builds. It's the official-style solution for deploying Rust on Heroku, offering reliability and integration with Heroku's ecosystem.
A buildpack for Rust applications on Heroku, with full support for Rustup, cargo and build caching.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Caches builds between deployments, significantly reducing build times for subsequent releases, as highlighted in the README's key features.
Uses the latest stable Rust by default with optional version pinning, ensuring up-to-date compiler features while allowing reproducibility through rust-toolchain files.
Can be combined with other buildpacks using multi-buildpack support, enabling seamless integration in applications that mix Rust with other languages like Ruby or Node.js.
Supports running Diesel database migrations during the release phase via RUST_INSTALL_DIESEL configuration, simplifying database management for Rust web apps on Heroku.
Exclusively designed for Heroku, making deployments to other clouds like AWS or Google Cloud impossible without significant rework, limiting flexibility.
Requires manual setup such as setting RUST_SKIP_BUILD for projects without a top-level Cargo.toml, adding complexity and potential for errors in mixed-language environments.
Relies on Heroku's Cedar stack with fixed time and resource limits, which can be restrictive for large Rust projects with long compilation times or heavy dependencies.
