Setup outside of main

emit is typically configured in your main function, but that might not be feasible for some applications. In these cases, you can run emit’s setup in a function and flush it deliberately at some later point:

#![allow(unused)]
fn main() {
extern crate emit;
extern crate emit_term;
fn diagnostics_init() {
    let _ = emit::setup()
        .emit_to(emit_term::stdout())
        .try_init();
}

fn diagnostics_flush() {
    emit::blocking_flush(std::time::Duration::from_secs(5));
}
}

Calling try_init() ensures you don’t panic even if setup is called multiple times.

emit doesn’t automatically flush or de-initialize its runtime when Init goes out of scope so it’s safe to let it drop before your application exits.
