Fix bug with PathAndArg config values This fixes an issue I noticed when trying to specify a target runner via the [`CARGO_TARGET_{triplet}_RUNNER`](https://doc.rust-lang.org/cargo/reference/config.html#targettriplerunner) environment variable, expecting it to override the value in our `.cargo/config.toml` file, which was giving quite strange errors until I figured out that cargo was actually merging the config file's values with the environment's values. This change adds a small hack to use and `UnmergedStringList` from `PathAndArgs` instead of just plain `StringList`, which uses the type in the deserializer to determine if `Config::get_list_or_string` should merge the values from the config file(s) with the environment as it was doing before, or else only use the environment to the exclusion of the config file(s) if the key was set in the environment. I also added a test for this to confirm both the bug and the fix.
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:
git
curl
(on Unix)pkg-config
(on Unix, used to figure out thelibssl
headers/libraries)- 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
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.
