    # Since stm32 crates take SO LONG to build, we split them
    # into a separate job. This way it doesn't slow down updating
    # the rest.
    strategy:
      matrix:
        crates:
          - stm32
          - rest

    # This will ensure at most one doc build job is running at a time
    # (for stm32 and non-stm32 independently).
    # If another job is already running, the new job will wait.
    # If another job is already waiting, it'll be canceled.
    # This means some commits will be skipped, but that's fine because
    # we only care that the latest gets built.
