Original GitHub issue: https://github.com/librespot-org/librespot/issues/358

When I tried to compile Librespot, I got these error messages:

error: aborting due to 6 previous errors

For more information about this error, try rustc --explain E0425.
error: Could not compile librespot-protocol.
warning: build failed, waiting for other jobs to finish...
error: build failed

I changed the constant in all of these files to "2_8_0" and it seems to work fine. I am no expert though, that's why leave this at "unsolved"

Edit: Could not get the code to be formatted in the right way

We should fix this by specifying an exact version of protobuf and protobuf-codege-pure until #293 is merged.

I get the same error but with 2_8_0 and 2_8_1. #293 works fine for me, I am currently using its branch https://github.com/willstott101/librespot/tree/protobuf-codegen-pure as a workarround.
