I'm working in a project using Trunk + Dioxus, so this happens when running trunk serve with the following code, it seems that somehow the Dioxus Component has something to to with it, if I change the Component type with a String rustc does not panic.

Code

use dioxus::prelude::*;

struct Wrapper {
  router: matchit::Router<(Component, Box<Self>)>,
}

impl Wrapper {
  fn at(&self, path: &str) -> Result<(Component, Box<Self>), matchit::MatchError> {
    // This code is clearly wrong, but the compiler crash
    let (cmp, router) = self.router.at("/")?;
    // If I write it correctly it does not crash
    // > let (cmp, router) = self.router.at("/")?.value;
    todo!()
  }
}
