Macro error_chain::quick_main
[−]
[src]
macro_rules! quick_main { ($main:expr) => { ... }; }
Convenient wrapper to be able to use try!
and such in the main. You can
use it with a separated function:
quick_main!(run); fn run() -> Result<()> { Err("error".into()) }
or with a closure:
quick_main!(|| -> Result<()> { Err("error".into()) });
You can also set the exit value of the process by returning a type that implements ExitCode
:
quick_main!(run); fn run() -> Result<i32> { Err("error".into()) }
