 When building a rust package in bitbake, it's usually easiest to build with
 cargo using cargo.bbclass.  If the package already has a Cargo.toml file (most
 rust packages do), then it's especially easy.  Otherwise you should probably

 Once your package builds in cargo, you can use
 [cargo-bitbake](https://github.com/meta-rust/cargo-bitbake) to generate a bitbake
 recipe for it.  This allows bitbake to fetch all the necessary dependent
 crates, as well as a pegged version of the crates.io index, to ensure maximum

-The master branch supports the latest master of poky. When poky creates releases, we will create a branch with the same name as the poky release. This release branch should always work with that poky release. Note that these release branches will typically be less tested than the master branch.

-All new patches against rust, rust-llvm, and cargo must have referenced
