error: macro expansion ignores token `assert_eq` and any following
|
|
--> $DIR/macro-in-expression-context.rs:12:9
|
|
|
|
|
LL | assert_eq!("B", "B");
|
|
| ^^^^^^^^^
|
|
...
|
|
LL | foo!()
|
|
| ------ caused by the macro expansion here
|
|
|
|
|
= note: the usage of `foo!` is likely invalid in expression context
|
|
help: you might be missing a semicolon here

LL | foo!();

warning: trailing semicolon in macro used in expression position

LL | assert_eq!("A", "A");

LL | foo!()

|
= 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: macro invocations at the end of a block are treated as expressions
|
|
= note: to ignore the value produced by the macro, add a semicolon after the invocation of `foo`
|
|
= note: `#[warn(semicolon_in_expressions_from_macros)]` on by default
|
|
= note: this warning originates in the macro `foo` (in Nightly builds, run with -Z macro-backtrace for more info)
