Formatting with --stdin and --rustfmt adds additional empty lines

[koopa1338]

I did set up my rust-analyzer as described in the readme and formatting works, however when formatting that way it adds 2 newlines at the end of each file.

A quick test shows that formatting with stdin flag outputs new lines at the end. I guess that formatting the output of the leptosfmt and piping that to rustfmt has a bug, keeping a newline. Here is a diff of the following commands:

cat src/main.rs | leptosfmt --stdin | rustfmt

cat src/main.rs | leptosfmt --stdin -r

diff:

mod app;

use app::*;
use leptos::*;

pub fn main() {
    _ = console_log::init_with_level(log::Level::Debug);
    console_error_panic_hook::set_once();

    mount_to_body(|| {
        view! { <App/> }
    });
}
+

Edit: It seems like multiple formats on the same file will add more empty lines
