Not a big issue, but I’m disappointed that diagnostic regression [`declare_interior_mutable_const` now fires in macros where it is meant to be allowed · Issue #12951 · rust-lang/rust-clippy · GitHub](https://github.com/rust-lang/rust-clippy/issues/12951) hasn't been fixed and is going to hit stable in this release.

</div>

the code compile error:

```rust
#[derive(Debug, Clone, thiserror::Error)]
pub enum Error {
    #[error("error when converting {source:?} to {target:?}")]
    ConvertError {
        source: String,
        target: String,
    },
}

```

because of `source` on v1.80.0.

```rust
error[E0599]: the method `as_dyn_error` exists for reference `&String`, but its trait bounds were not satisfied
   --> src/error.rs:34:9
    |
34 | source: String,
    | ^^^^^^ method cannot be called on `&String` due to unsatisfied trait bounds

```

> The Error trait’s `source()` method is implemented to return whichever field has a `#[source]` attribute or is named `source` , if any. This is for identifying the underlying lower level error that caused your error.
