Unable to build e01_basic_ping_bot about serenity HOT 6 OPEN

What version of Rust are you getting the error on? You can fetch this with rustc --version.

from serenity.

@GnomedDev I get rustc 1.75.0 (82e1608df 2023-12-21) when I run that command. There don't appear to be any updates available when running rustup check.

from serenity.

I would recommend running cargo clean and also cargo update. Your Cargo.lock may need to get refreshed.

That didn't seem to do anything.

That error message also seems a bit malformed. This isn't a valid function signature:

pub async fn dispatch(self, ctx: Context, handler: &mut dyn event_handler::EventHandler: &dyn EventHandler)

Also, the signature of FullEvent::dispatch in serenity v0.12.0 is this:

pub async fn dispatch(self, ctx: Context, handler: &dyn EventHandler)

from serenity.

@mkrasnitski I have no idea what's causing the malformed error message, but I reinstalled my toolchain as well as rust itself, tried switching from GNU to MSVC, and tested out the nightly toolchain with no result. What finally ended up working was just changing Serenity's version to v0.11.7. It doesn't really make any sense because I've been using v0.12.0 the whole time and the problem started spontaneously. I'll leave the issue open since my fix was to downgrade, so there must be something up with the current version of Serenity.
