Previously, `cargo metadata` exposed dependencies info as a graph of package id without any additional information on edges. However, we do want to add some data to edges, including for example, package renames and `cfg` info. Internally, the edges info is represented as a `Vec<Dependnecy>`. We could have exposed that directly, but that risks exposing and ossifying an implementation details. So instead we collapse a `Vec<Dependnecy>` to a single JSON object, which at the moment contains `id` and `rename` info only. It should be possible to add additional fields to that object backwards compatibly. Such representation does not correspond directly to any internal Cargo data structure, but hopefully it shouldn't be to hard to maintain. This representation also does not quite correspond to the "real world", where dependencies are between crate (cargo targets), and not packages. However, because each dep edge is a JSON object, adding a target filter should be possible, which would handle dev-, build-, and potential future bin-specific dependencies backwards-compatibly. |

Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.
Learn more at https://doc.rust-lang.org/cargo/
Code Status
Code documentation: https://docs.rs/cargo/
Installing Cargo
Cargo is distributed by default with Rust, so if you've got rustc
installed
locally you probably also have cargo
installed locally.
Compiling from Source
Cargo requires the following tools and packages to build:
python
curl
(on Unix)cmake
- OpenSSL headers (only for Unix, this is the
libssl-dev
package on ubuntu) cargo
andrustc
First, you'll want to check out this repository
git clone https://github.com/rust-lang/cargo
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
High level release notes are available as part of Rust's release notes. Cargo releases coincide with Rust releases.
Reporting issues
Found a bug? We'd love to know about it!
Please report all issues on the GitHub issue tracker.
