= help: remove the `#[macro_export]` or move this `macro_rules!` outside the of the current function `main`
|

= note: a `macro_rules!` definition is non-local if it is nested inside an item and has a `#[macro_export]` attribute
|
|
= note: one exception to the rule are anon-const (`const _: () = { ... }`) at top-level module

= 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>
