When using a macro in a place where a semicolon should not be at the end of the line:
warning: trailing semicolon in macro used in expression position
--> src/logging_macros.rs:29:49

29 | $crate::LOGGER.error(&format!($($arg)*));

::: src/lib.rs:283:23

283 | Err(_) => error!("Could not set timestamp format.")

= note: `#[warn(semicolon_in_expressions_from_macros)]` on by default
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #79813 <https://github.com/rust-lang/rust/issues/79813>
= note: this warning originates in the macro `error` (in Nightly builds, run with -Z macro-backtrace for more info)
