Packaging & Distribution

Ship Rust CLI binaries with cargo-dist, GitHub Releases, and package managers.

Recipe

cargo install cargo-dist
cargo dist init
cargo dist build

# dist.toml (generated / customized)
[workspace.metadata.dist]
cargo-dist-version = "0.28.0"
installers = ["shell", "powershell"]
targets = ["aarch64-apple-darwin", "x86_64-unknown-linux-gnu", "x86_64-pc-windows-msvc"]

When to reach for this: Public CLIs that need reproducible cross-platform release artifacts without manual CI scripting.

Working Example

# Cargo.toml
[package]
name = "mytool"
version = "0.1.0"
edition = "2024"
 
[workspace.metadata.dist]
# cargo dist reads this for release configuration

# .github/workflows/release.yml (simplified)
name: Release
on:
  push:
    tags: ['v*']
jobs:
  dist:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: dtolnay/rust-toolchain@stable
      - run: cargo dist build --artifacts=local
      - uses: softprops/action-gh-release@v2
        with:
          files: target/distrib/*

# User install via shell installer
curl --proto '=https' --tlsv1.2 -LsSf \
  https://github.com/org/mytool/releases/download/v0.1.0/mytool-installer.sh | sh

What this demonstrates:

cargo-dist builds per-target archives
Install scripts place binaries on PATH
GitHub Releases hosts versioned artifacts
Tag-driven workflow keeps releases reproducible

Deep Dive

Distribution Channels

Channel	Audience
`cargo install`	Rust developers
GitHub Releases	General users
Homebrew / nix	macOS / Linux power users
crates.io	Library + binary crate discovery

Static Linking for Portability

rustup target add x86_64-unknown-linux-musl
cargo build --release --target x86_64-unknown-linux-musl

musl binaries run on most Linux distros without glibc version issues.

Signing Releases

Sign checksums with cosign or GPG
Publish SHA256SUMS alongside archives
Document verification steps in README

Gotchas

Missing cross-compilation tools - Linux CI cannot build macOS binaries without cross tooling. Fix: Use cargo-dist's managed build matrix or platform-specific runners.
Glibc vs musl - Alpine containers need musl targets. Fix: Build separate musl artifacts or use static linking.
Stripped debug symbols - Harder to diagnose user crashes. Fix: Upload split debug symbols to your crash tracker.
License files omitted - Redistributors need LICENSE bundled. Fix: Include LICENSE and NOTICE in every archive.
Version not synced - Tag says v0.2.0 but Cargo.toml says 0.1.0. Fix: Automate version bumps in release workflow.

Alternatives

Alternative	Use When	Don't Use When
Manual `cross` + CI	Full control over build steps	You want installer generation too
`cargo-binstall`	Users already use binstall	You need custom install scripts
Docker images	Server-side CLI tools	Desktop developer tools

FAQs

cargo-dist vs cross?

cargo-dist orchestrates releases, installers, and CI. cross focuses on cross-compilation. They complement each other.

How do I publish to crates.io?

cargo publish after cargo dist tag. Binary users can cargo install mytool.

Homebrew formula?

Point the formula at GitHub release tarballs. Update SHA256 on each version bump.

Windows MSI installers?

cargo-dist supports WiX/MSI via its installer options. Enable in dist metadata.

Universal macOS binary?

Build both aarch64-apple-darwin and x86_64-apple-darwin, then lipo or ship separate archives.

SBOM for releases?

Generate with cargo cyclonedx or cargo auditable and attach to releases for supply chain compliance.

Pre-release channels?

Publish beta tags (v0.2.0-beta.1) to a separate GitHub prerelease channel.

Auto-update in the CLI?

Check GitHub Releases API on startup. Optional; respect corporate mirrors.

Minimum Rust version?

Set rust-version in Cargo.toml and enforce in CI so builds match user expectations.

Changelog automation?

Use git-cliff or release-plz to generate notes from conventional commits.
