Attribute Macro app 

#[app]

A macro that helps set up and run an Application.

This macro is meant to simplify the creation of arcon applications that do not require complex configuration. For more flexibility, have a look at ApplicationBulder.

Usage

With no arguments

#[arcon::app]
fn main() {
 (0..100u64)
    .to_stream(|conf| conf.set_arcon_time(ArconTime::Process))
    .map(|x| x * 10)
    .print()
}

Expands to the following

fn main() {
   use arcon::prelude::*;
   let mut builder = (0..100u64)
    .to_stream(|conf| conf.set_arcon_time(ArconTime::Process))
    .map(|x| x * 10)
    .print()
    .builder();

   builder
    .build()
    .run_and_block();
}
