# exit_status

[![Version info](https://img.shields.io/crates/v/exit_status.svg)](https://crates.io/crates/exit_status)

Simple proc-macro for enabling rust main function to return an exit status code.

## Example

```rust

#[exit_status::main]

fn main() -> anyhow::Result {

    Ok(0)

}

// expands to

// fn main() -> anyhow::Result<()> {

//     fn inner_main() -> anyhow::Result {

//         {

//             Ok(0)

//         }

//     }

//     std::process::exit(inner_main()?);

// }

```
