feat(install): Support `foo@version` like cargo-add ### What does this PR try to resolve? This aims to make `cargo install` consistent with - `cargo add foo@version` from #10472 - pkgid changes in #10582 - `cargo yank foo@version` from #10597 It also offers a shorthand for people installing a specific version. ### How should we test and review this PR? #10582 acted as the FCP for this, see #10597 Documentation updates are split into their own commit to not clog up browsing the code. Examine the tests to see if they make sense ### Additional information While the `foo@vewrsion` syntax is the same, each's semantics are different. We had decided it was better to have the same syntax with different semantics than having the user worry about what syntax they use where. In `cargo install`s case, it has an implicit-but-required `=` operand while `cargo-add` allows any operand. This doesn't use the full `pkgid` syntax because that allows syntax that is unsupported here. This doesn't use `cargo-add`s parser because that is for version reqs. I held off on reusing the parser from `cargo-yank` because they had different type system needs and the level of duplication didn't seem worth it (see Rule of Three).
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.
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:
gitcurl(on Unix)pkg-config(on Unix, used to figure out thelibsslheaders/libraries)- OpenSSL headers (only for Unix, this is the
libssl-devpackage on ubuntu) cargoandrustc
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
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 this repo at CHANGELOG.md.
