Description
hey, I've been trying to get the example from https://docs.rs/xilem/latest/xilem/ to run, but I get this error:

Ok(())
}and this is my Cargo.toml:
[package]
name = "messages"
version = "0.1.0"
edition = "2024"
[dependencies]
winit = { version = "0.30.12", features = ["wayland"] }
xilem = "0.4.0"I an on FreeBSD 14.3 and am running the sway window manager(on wayland).
does anyone have any idea what the problem could be? it appears to be that wgpu didn't detect any graphics backend but I guess it could be that FreeBSD just isn't supported.
