A Cargo command for managing buildpacks written with libcnb.rs.
shell
$ cargo install libcnb-cargo
Currently, there is only one sub-command: package
. It allows users to package their
Rust buildpack in a spec-compliant manner and helps with cross-compilation.
```shell $ cargo libcnb package --help Packages a libcnb.rs Cargo project as a Cloud Native Buildpack
Usage: cargo libcnb package [OPTIONS]
Options:
--no-cross-compile-assistance Disable cross-compile assistance
--release Build in release mode, with optimizations
--target
Using it is fairly simple, run cargo libcnb package
inside the buildpack's
project directory:
```shell $ cargo libcnb package 🚚 Preparing package directory... 🖥️ Gathering Cargo configuration (for x86_64-unknown-linux-musl) 🏗️ Building buildpack dependency graph... 🔀 Determining build order... 🚚 Building 1 buildpacks... 📦 [1/1] Building libcnb-examples/my-buildpack (./)
Finished dev [unoptimized] target(s) in 8.24s
Successfully wrote buildpack directory: packaged/x8664-unknown-linux-musl/debug/libcnb-examplesmy-buildpack (4.09 MiB) ✨ Packaging successfully finished!
💡 To test your buildpack locally with pack, run: pack build my-image-name \ --buildpack packaged/x8664-unknown-linux-musl/debug/libcnb-examplesmy-buildpack \ --path /path/to/application
/Users/example/src/my-buildpack/packaged/x8664-unknown-linux-musl/debug/libcnb-examplesmy-buildpack ```
