Macro si_trace_print::de

macro_rules! de {
    (
        $($args:tt)*
    ) => { ... };
}

debug eprintln!

For completeness, wrap eprintln!.

use si_trace_print::{defn, defx};
use si_trace_print::de;
fn func1() {
    de!("hello");
}
fn main() {
    defn!();
    func1();
    defx!();

prints

→main:
hello
←main:
