The Playground [0] and cargo-script [1] are the best options atm. In some respects, I think I prefer these. The only downside is the lack of introspection which is diminished by the use of static typing. [0] https://play.rust-l

Does build-plan help with the case of including an artifact from another build system (e.g. data file for code-generation like SVD or libs to link against)? What about someone not using build-plan but publishing crates, whether external or

I wholeheartedly agree with K&R. A lot of the hard problems I've debugged have been the interaction of multiple state machines. In these cases I needed to see the forest of interactions rather than the trees of instructions. On t

No, I have not written a GUI in Rust yet. I've been doing libraries and CLIs so far. But I find the standard approaches to GUI broken: inheritance and shared mutable state. i think Rust does a service by highlighting the brittleness

> 1. I find it odd that some things like slice reads can still panic by default. Yes, I can use `foo.get(1)` to avoid panics, but still - it's a bit odd to me. I wonder if this is similar to C++'s `[]` vs `at`. `at` does impli

The concern over fragmentation is why believe conan's approach is the best: decouple dependency management from build rather than forcing everyon to align on build. Still has its hurdles but it is a step in the right direction for tryi

This looks really nice. I'll have to give this a try at some point to see how I feel about it vs Azure Pipelines. From my quick look, this looks more general purpose at the cost of more verbosity.

I feel dirty for saying this but Azure Pipelines is the service that is tempting to me because of the power of its file format (variable substitution, conditionals, template tasks and steps).

`failure` captures common error patterns in Rust and provided a test bed for experimenting on them while working to improve `trait Error`. There is an RFC for pulling some of the trait improvements into the language. After that, I believe
