# README

Control macros for `Option` and `Result`.

Helps you change this:

```rust

fn returns_early_with_value(input: Result) {

    // Early return when something is wrong.

    let input: i32 = match input {

        Ok(value) => value,

        Err(_) => return,

    };

    // Use it normally below...

    println!("Input is: {}", input);

}

```

into

```rust

use ctrl_macros::{ok_or_return};

fn returns_early_with_value(input: Result) {

    let input: i32 = ok_or_return!(input);

    println!("Input is: {}", input);

}

```

## Examples

```rust

let x = ok_or!(x, return 42);

```

```rust

for i in 0..5 {

    let x = ok_or_continue!(x);

}

```

```rust

for i in 0..5 {

    let x = ok_or_break!(x);

}

```

and `some_or` equivalents

```rust

some_or!

some_or_return!

some_or_continue!

some_or_break!

```
