[INFO] [stdout]    = note: this method call relies on the `impl<T> Into<T> for T` blanket implementation and type inference, which is a semver hazard as a new `impl Into<_>` that affects your type might be added in the future causing type inference errors
[INFO] [stdout] help: consider removing the conversion call
