array-fu

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.
