[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]    = note: you can instead use the fully-qualified path `<cgmath::Vector3<f32> as Into<cgmath::Vector3<f32>>::into(val) to avoid triggering this lint
