[-Zbuild-std] Only build libtest when libstd is built Currently `libtest` is always compiled when a compilation unit uses a test harness. This implicitly adds builds the standard library too because `libtest` depends on it. This breaks the use of custom test frameworks in `no_std` crates as reported in https://github.com/rust-lang/cargo/pull/7216#issuecomment-529433594. This pull request fixes the issue by only building `libtest` if `libstd` is built. This makes sense in my opinion because when the user explicitly specified `-Zbuild-std=core`, they probably don't want to build the full standard library and rather get a compilation error when they accidentally use `libtest`.
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:
gitpythoncurl(on Unix)- 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.
