Installation

Homebrew (recommended)

brew install pallewela/tap/rusta

This installs the latest prebuilt aarch64-apple-darwin binary from the GitHub Releases page. Upgrades land via brew upgrade rusta.

Manual download

Grab the tarball for the release you want from GitHub Releases, then:

tar -xzf rusta-vX.Y.Z-aarch64-apple-darwin.tar.gz
install -m 0755 rusta /usr/local/bin/rusta

The tarball also ships shell completions and man pages under share/. Install them alongside the binary:

# man pages
sudo install -d /usr/local/share/man/man1
sudo install -m 0644 share/man/man1/*.1 /usr/local/share/man/man1/

# zsh completions (adjust to your $fpath)
sudo install -m 0644 share/zsh/site-functions/_rusta /usr/local/share/zsh/site-functions/

# bash / fish — install to your shell's standard completion path

Each release page lists the SHA256 of the tarball; verify with shasum -a 256 before installing.

From crates.io

cargo install rusta-cli

The crate is named rusta-cli on crates.io because rusta was already taken; the installed binary is still rusta.

From source

cargo install --path .
# or
cargo install --git https://github.com/pallewela/rusta

Shell completions

If you installed via cargo install or built from source, the prebuilt completion scripts aren’t on disk — generate them yourself at any time:

rusta completions bash > /usr/local/etc/bash_completion.d/rusta
rusta completions zsh  > "${fpath[1]}/_rusta"
rusta completions fish > ~/.config/fish/completions/rusta.fish

Homebrew installs and the Manual download tarball already include these under share/, so no extra step is needed there.
