[unstable option] empty_item_single_line

Tracking issue for unstable option: empty_item_single_line

[Emoun]

Hi,

I hope this is the right place to report this:

When the option brace_style is set to "AlwaysNextLine", then empty_item_single_line=true does not work for traits:

// Expected:
pub trait SomeTrait {}

// Produced:
pub trait SomeTrait 
{
}

Removing the brace_style option from the .toml will make rustfmt produce the expected formatting.

When using empty_item_single_line=false with the following code

mod hello {
}

fn foo() {
}

I get this result

mod hello {}

fn foo() {
}

but I would expect this result

mod hello {
}

fn foo() {
}
