[INFO] [stdout]    = help: move this `impl` block outside the of the current constant `_IMPL_DECODE_FOR_RawEvent`
[INFO] [stdout]    = note: an `impl` definition is non-local if it is nested inside an item and neither the type nor the trait are at the same nesting level as the `impl` block
[INFO] [stdout]    = note: this lint may become deny-by-default in the edition 2024 and higher, see the tracking issue <https://github.com/rust-lang/rust/issues/120363>
[INFO] [stdout]    = note: this error originates in the derive macro `$crate::codec::Decode` which comes from the expansion of the macro `decl_event` (in Nightly builds, run with -Z macro-backtrace for more info)
