Project doesn't build - can't find ptr::from_ref

[binarymax]

Hi! I cloned the repo and ran cargo build and I get the following error:

error[E0425]: cannot find function `from_ref` in module `ptr`
   --> src/task/server.rs:246:37
    |
246 |             drop(Box::from_raw(ptr::from_ref(config).cast_mut()));
    |                                     ^^^^^^^^ not found in `ptr`
    |

I am using rustc/cargo version 1.60.0 (on Ubuntu 20.04)

Any advice?

Did some digging and looks like I need a new version of Rust! rust-lang/rust#106116

Well, I used a nightly version for this project, you can use rustup override set nightly while located in the project directory and then try to build it again. If you want to use the stable version, you have to modify that line of code:

drop(Box::from_raw(config as *mut Server));

Not sure if that will compile, I can't test it right now. I'll check later to confirm.

I just used nightly and got it to build. Thanks for the quick response!
