This is a replacement for
Eric Fode's excellent
heroku-buildpack-rust, but with support for
recent Rust nightly builds and Cargo. The intention is that this
will involve into a production-quality, supported buildpack as Rust and
This is now the supported way of using this buildpack. For instructions and example code, see Deploying Rust applications to Heroku, with example code for Iron and heroku-rust-cargo-hello.
The older support for
git submodule-based projects is deprecated, and
will be phased out at some point.
If you need to tweak this buildpack, the following information may help.
To test changes to the buildpack using the included
cp -a ../heroku-rust-cargo-hello . # Or whatever you want to test. vagrant up vagrant ssh cd /vagrant mkdir cache bin/compile `pwd`/heroku-rust-cargo-hello `pwd`/cache # Then make sure there are no Rust-related *.so files getting linked: ldd heroku-rust-cargo-hello/target/hello
This gives you a system a lot like Heroku's Cedar stack, except that you can debug it locally.
Copy the snippet above into CLI.
