bors b64c96bfa0 Auto merge of #9793 - nipunn1313:install_parallel2, r=alexcrichton
Determine packages to install prior to installing

Old logic (pseudocode)
```
for krate in to_install {
    pkg = determine_pkg(krate);
    install_pkg(pkg);
}
```
New logic
```
let pkgs = to_install.into_iter(|krate| determine_pkg(krate));
pkgs.into_iter(|pkg| install_pkg(pkg));
```

This has the short term benefit of dumping most error messages out earlier in the process (eg a typo in the second package name).

Longer term, it might help with #9741 - as only the second loop would be parallelized. First loop shouldn't be parallelized because it would lead to redundant registry/git updates.

Cargo

Cargo downloads your Rust projects dependencies and compiles your project.

Learn more at https://doc.rust-lang.org/cargo/

Code Status

Build 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:

  • git
  • curl (on Unix)
  • pkg-config (on Unix, used to figure out the libssl headers/libraries)
  • OpenSSL headers (only for Unix, this is the libssl-dev package on ubuntu)
  • cargo and rustc

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.

Reporting issues

Found a bug? We'd love to know about it!

Please report all issues on the GitHub issue tracker.
