Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.
To start using Cargo, learn more at The Cargo Book.
To start developing Cargo itself, read the Cargo Contributor Guide.
The Cargo binary distributed through with Rust is maintained by the Cargo team for use by the wider ecosystem. For all other uses of this crate (as a binary or library) this is maintained by the Cargo team, primarily for use by Cargo and not intended for external use (except as a transitive dependency). This crate may make major changes to its APIs.
Code Status
Code documentation: https://doc.rust-lang.org/nightly/nightly-rustc/cargo/
Compiling from Source
Requirements
Cargo requires the following tools and packages to build:
cargo
andrustc
- A C compiler for your platform
git
(to clone this repository)
Other requirements:
The following are optional based on your platform and needs.
-
pkg-config
— This is used to help locate system packages, such aslibssl
headers/libraries. This may not be required in all cases, such as using vendored OpenSSL, or on Windows. -
OpenSSL — Only needed on Unix-like systems and only if the
vendored-openssl
Cargo feature is not used.This requires the development headers, which can be obtained from the
libssl-dev
package on Ubuntu oropenssl-devel
with apk or yum or theopenssl
package from Homebrew on macOS.If using the
vendored-openssl
Cargo feature, then a static copy of OpenSSL will be built from source instead of using the system OpenSSL. This may require additional tools such asperl
andmake
.On macOS, common installation directories from Homebrew, MacPorts, or pkgsrc will be checked. Otherwise it will fall back to
pkg-config
.On Windows, the system-provided Schannel will be used instead.
LibreSSL is also supported.
Optional system libraries:
The build will automatically use vendored versions of the following libraries. However, if they are provided by the system and can be found with pkg-config
, then the system libraries will be used instead:
libcurl
— Used for network transfers.libgit2
— Used for fetching git dependencies.libssh2
— Used for SSH access to git repositories.libz
(aka zlib) — Used for data compression.
It is recommended to use the vendored versions as they are the versions that are tested to work with Cargo.
Compiling
First, you'll want to check out this repository
git clone https://github.com/rust-lang/cargo.git
cd cargo
With cargo
already installed, you can simply run:
cargo build --release
Adding new subcommands to Cargo
Cargo is designed to be extensible with new subcommands without having to modify Cargo itself. See the Wiki page for more details and a list of known community-developed subcommands.
Releases
Cargo releases coincide with Rust releases. High level release notes are available as part of Rust's release notes. Detailed release notes are available in the changelog.
