Is this an `E` error? Returns true if any error in the context chain is an `E`. # Example ``` # use wasmtime_internal_core as wasmtime; use wasmtime::error::{Error, OutOfMemory}; let oom = Error::from(OutOfMemory::new(1234)); assert!(oom.is:: ()); assert!(!oom.is:: ()); // Here is an example with additional error context. let error = Error::from(u8::try_f

    pub fn is<E>(&self) -> bool
    where
        E: fmt::Display + fmt::Debug + Send + Sync + 'static,
    {
        self.error_ext_chain().any(|e| {
            let result = e.inner.is::<E>();

            #[cfg(feature = "anyhow")]
            let result = result
                || e.inner
                    .downcast_ref::<anyhow::Error>()
                    .is_some_and(|e| e.is::<E>());

            result
        })
    }

    /// Downcast this error into an `E`, taking ownership.
