[Doc comment on impl blocks shows the first line, even when the impl block is collapsed](https://redirect.github.com/rust-lang/rust/pull/132155) <a id="1.85.0-Compatibility-Notes"></a> ## Compatibility Notes - [`rustc` no longer treats the `test` cfg as a well known check-cfg](https://redirect.github.com/rust-lang/rust/pull/131729), instead it is up to the build systems and users of `--check-cfg`\[^check-cfg] to set it as a well known cfg using `--check-cfg=cfg(test)`. This is done to enable build systems like Cargo to set it conditionally, as not all source files are suitable for unit tests. [Cargo (for now) unconditionally sets the `test` cfg as a well known cfg](https://redirect.github.com/rust-lang/cargo/pull/14963). \[^check-cfg]: https://doc.rust-lang.org/nightly/rustc/check-cfg.html - [Disable potentially incorrect type inference if there are trivial and non-trivial where-clauses](https://redirect.github.com/rust-lang/rust/pull/132325) - `std::env::home_dir()` has been deprecated for years, because it can give surprising results in some Windows configurations if the `HOME` environment variable is set (which is not the normal configuration on Windows). We had previously avoided changing its behavior, out of concern for compatibility with code depending on this non-standard configuration. Given how long this function has been deprecated, we're now fixing its behavior as a bugfix. A subsequent release will remove the deprecation for this function. - [Make `core::ffi::c_char` signedness more closely match that of the platform-default `char`](https://redirect.github.com/rust-lang/rust/pull/132975) This changed `c_char` from an `i8` to `u8` or vice versa on many Tier 2 and 3 targets (mostly Arm and RISC-V embedded targets). The new definition may result in compilation failures but fixes compatibility issues with C. The `libc` crate matches this change as of its 0.2.169 release. - [When compiling a nested `macro_rules` macro from an external crate, the content of the inner `macro_rules` is now built with the edition of the external crate, not the local crate.](https://redirect.github.com/rust-lang/rust/pull/133274) - [Increase `sparcv9-sun-solaris` and `x86_64-pc-solaris` Solaris baseline to 11.4.](https://redirect.github.com/rust-lang/rust/pull/133293) - [Show `abi_unsupported_vector_types` lint in future breakage reports](https://redirect.github.com/rust-lang/rust/pull/133374) - [Error if multiple super-trait instantiations of `dyn Trait` need associated types to be specified but only one is provided](https://redirect.github.com/rust-lang/rust/pull/133392) - [Change `powerpc64-ibm-aix` default `codemodel` to large](https://redirect.github.com/rust-lang/rust/pull/133811) <a id="1.85.0-Internal-Changes"></a> ## Internal Changes These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Build `x86_64-unknown-linux-gnu` with LTO for C/C++ code (e.g., `jemalloc`)](https://redirect.github.com/rust-lang/rust/pull/134690) </details> --- ### Configuration 📅 **Schedule**: Branch creation - "* * * * *" (UTC), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

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.
The Cargo binary distributed through with Rust is maintained by the Cargo team for use by the wider ecosystem. For all other uses of this crate (as a binary or library) this is maintained by the Cargo team, primarily for use by Cargo and not intended for external use (except as a transitive dependency). This crate may make major changes to its APIs.
Code Status
Code documentation: https://doc.rust-lang.org/nightly/nightly-rustc/cargo/
Compiling from Source
Requirements
Cargo requires the following tools and packages to build:
cargoandrustc- A C compiler for your platform
git(to clone this repository)
Other requirements:
The following are optional based on your platform and needs.
-
pkg-config— This is used to help locate system packages, such aslibsslheaders/libraries. This may not be required in all cases, such as using vendored OpenSSL, or on Windows. -
OpenSSL — Only needed on Unix-like systems and only if the
vendored-opensslCargo feature is not used.This requires the development headers, which can be obtained from the
libssl-devpackage on Ubuntu oropenssl-develwith apk or yum or theopensslpackage from Homebrew on macOS.If using the
vendored-opensslCargo feature, then a static copy of OpenSSL will be built from source instead of using the system OpenSSL. This may require additional tools such asperlandmake.On macOS, common installation directories from Homebrew, MacPorts, or pkgsrc will be checked. Otherwise it will fall back to
pkg-config.On Windows, the system-provided Schannel will be used instead.
LibreSSL is also supported.
Optional system libraries:
The build will automatically use vendored versions of the following libraries. However, if they are provided by the system and can be found with pkg-config, then the system libraries will be used instead:
libcurl— Used for network transfers.libgit2— Used for fetching git dependencies.libssh2— Used for SSH access to git repositories.libz(aka zlib) — Used for data compression.
It is recommended to use the vendored versions as they are the versions that are tested to work with Cargo.
Compiling
First, you'll want to check out this repository
git clone https://github.com/rust-lang/cargo.git
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 the changelog.
Reporting issues
Found a bug? We'd love to know about it!
