Version: wasabi-0.1.4-3-g6384482

[arduano]

I believe I pinned the rust version in latest master, could you check that? Otherwise MBMS has helped patch the issues in midi-toolkit-rs, I'll get around to merging them in eventually. This is just rust nightly breaking changes

[yurivict]

We use pre-built rust-nightly package, and can't use pinned rust-nightly because these nightlies are already available (or never been available) as packages.

[arduano]

I'm not sure what you're talking about, are you using rustup?

[yurivict]

The failure is in the FreeBSD port audio/wasabi which uses the rust-nightly package.

[arduano]

oh, so the build system doesn't allow switching toolchains to the one wasabi is pinned to? that's kinda annoying and sounds like a build system issue not a wasabi issue. Generally you're supposed to use rustup which automatically manages toolchains for you.

I'll update the toolchain to the latest sometime, just busy rn (PRs welcome btw)
