This crate defines [`array!`] and other macros that can construct arrays.

Use simple syntax, make it more complex as requirements change.

[`array!`] macro constructs arrays by repeating expression execution, possibly with enumeration bound to provided pattern.

# Examples

```

use array_fu::array;

use rand::random;

let values: [f32; 2] = array![random(); 2];

```

This also means that expression type may not be `Copy` or event `Clone`.

```

use array_fu::array;

# use std::sync::Mutex;

let values = array![Mutex::new(1); 2];

```

See more examples in the [`array!`] macro documentation.

[`collect_array!`] macro constructs arrays by repeating expression execution with elements from iterators bound to provided patterns.

# Examples

```

use array_fu::collect_array;

let opt = collect_array![x in 1.., y in 2.. => x + y; where x * y > 10; 3];

assert_eq!(opt, Some([7, 9, 11]));

```

```

use array_fu::collect_array;

let values = collect_array![(x, y) in [(1, 2), (3, 4), (5, 6)] => x + y; 3];

assert_eq!(values, Some([3, 7, 11]));

```

See more examples in the [`collect_array!`] macro documentation.
