assertion failed: !value.has_escaping_bound_vars() #101984
Description
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!() } }Meta
