You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: trinket-pro-blink.rs
    path of file: ./repos/avr-hal/examples/trinket-pro/src/bin
    
    the code of the file until where you have to start completion: #![no_std]
#![no_main]

use panic_halt as _;

#[arduino_hal::entry]
fn main() -> ! {
    let dp = arduino_hal::Peripherals::take().unwrap();
    let pins = arduino_hal::pins!(dp);

    // Digital pin 13 is also connected to an onboard LED marked "L"
    let mut led = pins.d13.into_output();
    led.set_high();

    loop {
        led.toggle();
        arduino_hal::delay
    
fn main() -> ! {
    let dp = arduino_hal::Peripherals::take().unwrap();
    let pins = arduino_hal::pins!(dp);

    let mut led = pins.d13.into_output();
