![]() Rust # pub fn greet (name : & str ) s, where variables will be interpolated. Learn how to set up Cargo with Artifactory. Artifactory supports version management for Rust packages, too, so that you can easily keep track of releases and archive older packages. You can also cache Cargo packages locally with Artifactory, which makes it easier to work with Cargo offline and improves performance by eliminating the need to download dependencies or other data from the Internet before building a new Cargo package. Local repositories are especially useful for businesses that need to share Cargo packages internally and want to avoid the security and performance issues associated with distributing them through a public registry. In addition to interacting directly with packages hosted on Crates.io, Artifactory lets you create private, local Cargo repositories, where you have more control over access configurations than Crates.io supports. You can get even more functionality and features out of Cargo by combining it with JFrog Artifactory as a Cargo registry. Enhancing Rust package management with Artifactory While there’s nothing technically stopping you from hosting compiled Rust packages elsewhere, such as on GitHub, Rust developers discourage this practice because they aim to make Crates.io the official, trusted package registry for the Rust community. In other words, Crates.io is to Rust what Docker Hub is to Docker. Crates.io is a public registry for hosting and distributing Rust packages. ![]() ![]() But what if you want to deploy it to a production system (which is presumably not the same as your local build system) or share the application with other users? Now, you can run the application with a simple:Ĭargo run Deploying Rust packages with Crates.ioĪt this point, you have a Rust package that you can run locally. The compiler will generate binaries and store them in a new subdirectory called target/ which exists alongside the src/ directory of your package. With your source code in place and your Cargo.toml file updated, you can build the package: You’ll also need to modify Cargo.toml to fit the configuration of your application and any dependencies. To deploy a real-world app, however, you’ll first need to move your source file or files for the app into the src/ directory of your package:Ĭp /path/to/your/source/file.rs your_project_name/src You can go right ahead and build these files, if you just want to deploy Rust’s Hello World! program. Main.rs is a Rust source file for a Hello World! program that Cargo creates by default. A src/ directory, which contains a file called main.rs.You’ll see that Cargo creates a new directory in your present working directory called your_project_name. To use Cargo, you first need to create a package: How to manage Rust packages with CargoĬargo’s syntax and methodology are quite straightforward. That said, Cargo can be used to manage code written in other languages, including C, which is useful if you’re developing an application that includes other code in addition to Rust source code. Cargo lets you create packages by combining crates together, as well as build and deploy those packages.Ĭargo is similar to tools like Make (which can also be used to build Rust packages, if desired), but it is purpose-built by the Rust community for managing Rust packages specifically. What is Cargo?Ĭargo is a tool for building and managing Rust packages. You can think of Rust packages as being akin to Docker images or Debian packages, with the main difference being that Rust packages include source code that must be compiled before it can be deployed. Note that you may sometimes hear Rust developers use the terms “crate” and “package” interchangeably, but technically, there is a difference: A crate is an individual component of a package, while a package is what you get when you pair one or more crates with a deployment configuration file (i.e., the Cargo.toml file). The source files and libraries are known as crates. A configuration file, called Cargo.toml, that defines how the various other components of the package should be put together to deploy a usable application or service.Optionally, a library file, if the source code files require a library to run.One or more Rust source code files, which contain the code to implement whichever functionality the package aims to supply.In Rust, a package is a set of files that can be used to deploy an application written in Rust. Keep reading for a primer on how to manage Rust packages using Cargo. But another standout feature of Rust is that, unlike many other languages, it provides its very own build system and package manager, which is known as Cargo. Rust is well-known for being a programming language that focuses on security.
