#[discard_params_doc]
trait Trait {
fn foo(
&self,
/// some docs
bar: String,
/// another docs
baz: i32,
);
}
$ cargo run --bin rustfmt -- --edition=2018 < example.rs 2> /dev/null
#[discard_params_doc]
trait Trait {
fn foo(&self, /// some docs bar: String, /// another docs baz: i32
);
}
Normally doc comments on fn params triggers compile error. But it's ok if attribute macro discards it anyway... unless I run rustfmt on it.
