That's cool. I was not able to repro due to the buck2 instructions not working for me, two different ways
Compiling gazebo v0.8.1 (/home/jwb/buck2/gazebo/gazebo)
error[E0554]: `#![feature]` may not be used on the stable release channel
--> gazebo/gazebo/src/lib.rs:10:49
Then with the alternate instructions:
error: no such command: `+nightly-2023-01-24`
Cargo does not handle `+toolchain` directives.
Did you mean to invoke `cargo` through `rustup` instead?
