RustAudio
can't compile HEAD; "two different versions of nix"
Hi - new to the project and excited to dive in. But I grabbed the head and tried to compile, and it dies with:
error[E0308]: mismatched types
--> src/host/alsa/mod.rs:248:26

244 | let handle = match handle_result {

= note: perhaps two different versions of crate nix are being used?
And sure enough, there are:
git clone https://github.com/RustAudio/cpal
cd cpal
cargo build

Updating cpal's Cargo.toml to the newest version seems to fix the compile (happy to submit the trivial patch), but I don't know enough about the project yet to see if that's an OK fix. Trivially, all of the tests in 'cargo test' work. Feedback welcome.
(Oh - and thanks for the cool project!)

Looks like this also affects rodio (version 0.14) because of it's dependency on cpal release 0.13.
Pull request to fix here: https://github.com/RustAudio/cpal/pull/609
i am still getting this error in 0.14 when compiling on linux without jack.
