pin nightly version to 2018-05-16 #3

Build is broken with latest nightly due to [panic_fmt removal]:
~/.cargo/registry/src/github.com-1ecc6299db9ec823/panic-abort-0.1.1/src/lib.rs:25:1

25 | #[lang = "panic_fmt"]
| ^^^^^^^^^^^^^^^^^^^^^ definition of unknown language item `panic_fmt`
Upgrading to newer panic-abort bumps into proc-macro2 issues
described in rtic-rs/rtic-syntax#7 .
Stumbled onto this when investigating a [build failure] for atsamd-rs#2.

I would prefer a solution that removes RTFM from the metro_m0 examples crate - I'm not sure it's best to tie this entire library to an old nightly because of one example. This would also block this library from moving to stable (if desired). |
|
I was thinking of this as a stop-gap to fix CI (see #2) and make it less confusing for newcomers until either RTFM can be fixed or, as you said, removed from the examples. But I totally understand where you are coming from. |

@bfritz thanks for posting the workaround. |
|
Thanks for this; I want to unblock using more recent nightly builds so that we won't need to pin back. I've taken a stab at that in #4 and would appreciate your input to resolve a linker error. |
|
I'll merge this in the meantime; thanks! |

Stumbled onto this when investigating a build failure for #2. Affected #1 (comment) too.
