Allow printing defmt output to the RTT console #880

Oh, and defmt-print must be installed for this to work. Maybe add a tooltip for that? |

@haneefdm Do you have questions about this? |

Thank you for the PR and I agree it will be very useful for Rust developers Before I look at it, I have a request. I need an example project available on github for me to begin looking at it. It will be my test case as well. Your github example project should be ready to run with minimal effort on my part (preferably on a Mac). I cannot accept what I cannot test. I am not Rust-educated either. I you can also update the source code to add a reference to the example github then that would be nice. Sorry, it took me a long time to get to it. Personal health reasons. |

I'll get back to this in a few days. I need to refresh my memory after taking care of some other stuff. |

Any updates? I got the same problem, cortex-debug cannot print defmt's RTT log |

Installed extension from this PR, everything works perfectly, except vscode does not hint to set |

@xoviat I am still waiting for the PRs original author. |
defmt is widely used as a logger in the rust embedded ecosystem. This allows seamlessly debugging a rust program while printing defmt output at the same time.
