cargo binstall provides a low-complexity mechanism for installing rust binaries as an alternative to building from source (via cargo install) or manually downloading packages. This is intended to work with existing CI artifacts and infrastructure, and with minimal overhead for package maintainers.

binstall works by fetching the crate information from crates.io, then searching the linked repository for matching releases and artifacts, with fallbacks to quickinstall and finally cargo install if these are not found. To support binstall maintainers must add configuration values to Cargo.toml to allow the tool to locate the appropriate binary package for a given version and target. See SUPPORT.md for more detail.

You probably want to see this page as it was when the latest version was published for accurate documentation.

Here are the one-liners for installing pre-compiled cargo-binstall binary from release on Linux and macOS:

curl -L --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/cargo-bins/cargo-binstall/main/install-from-binstall-release.sh | bash

And the one-liner for installing a pre-compiled cargo-binstall binary from release on Windows (x86_64 and aarch64):

Set-ExecutionPolicy Unrestricted -Scope Process; iex (iwr "https://raw.githubusercontent.com/cargo-bins/cargo-binstall/main/install-from-binstall-release.ps1").Content

To get started using cargo-binstall first install the binary (either via cargo install cargo-binstall or by downloading a pre-compiled release), then extract it using tar or unzip and move it into $HOME/.cargo/bin. We recommend using the pre-compiled ones because we optimize those more than a standard source build does.

We also provide pre-built artifacts with debuginfo for Linux and Mac. These artifacts are suffixed with .full.tgz on Linux and .full.zip on Mac and Windows.

To upgrade cargo-binstall, use cargo binstall cargo-binstall!

Supported packages can be installed using cargo binstall NAME where NAME is the crates.io package name.

Package versions and targets may be specified using the --version and --target arguments respectively, and will be installed into $HOME/.cargo/bin by default. For additional options please see cargo binstall --help.

Nowadays, cargo-binstall is smart enough. All you need just passing the crate name.

cargo binstall --no-confirm --no-symlinks cargo-edit cargo-watch cargo-tarpaulin \
    watchexec-cli cargo-outdated just fnm broot stylua

If your favorite package fails to install, you can instead specify the pkg-url, bin-dir, and pkg-fmt at the command line, with values as documented in SUPPORT.md.

For example:

$ cargo-binstall \
  --pkg-url="{ repo }/releases/download/{ version }/{ name }-{ version }-{ target }.{ archive-format }" \
  --pkg-fmt="txz" \
  crate_name

The most ergonomic way to upgrade the installed crates is with cargo-update. cargo-update automatically uses cargo-binstall to install the updates if cargo-binstall is present.

Supported crates such as cargo-binstall itself can also be updated with cargo-binstall as in the example in Installation above.

• Why use this?
  • Because wget-ing releases is frustrating, cargo install takes a not inconsequential portion of forever on constrained devices, and often putting together actual packages is overkill.
• Why use the cargo manifest?
  • Crates already have these, and they already contain a significant portion of the required information. Also, there's this great and woefully underused (IMO) [package.metadata] field.
• Is this secure?
  • Yes and also no? We're not (yet? #1) doing anything to verify the CI binaries are produced by the right person/organization. However, we're pulling data from crates.io and the cargo manifest, both of which are already trusted entities, and this is functionally a replacement for curl ... | bash or wget-ing the same files, so, things can be improved but it's also fairly moot
• What do the error codes mean?
  • You can find a full description of errors including exit codes here: https://docs.rs/binstalk/latest/binstalk/errors/enum.BinstallError.html
• Can I use it in CI?
  • Yes! For GitHub Actions, we recommend the excellent taiki-e/install-action, which has explicit support for selected tools and uses cargo-binstall for everything else.
• Are debug symbols available?
  • Yes! Extra pre-built packages with a .full suffix are available and contain split debuginfo, documentation files, and extra binaries like the detect-wasi utility.

If you have ideas/contributions or anything is not working the way you expect (in which case, please include an output with --log-level debug) and feel free to open an issue or PR.
