Trait core_extensions::collections::IntoArray

source · [−]
pub trait IntoArray {
    type Array;

    fn into_array(self) -> Self::Array;
}
Available on crate feature collections only.
Expand description

Converts a fixed length collection to an array.

Features

Enabling the “rust_1_51” feature allows arrays of all lengths to implement this trait, otherwise it’s only implemented for arrays up to 32 elements long.

Examples

Tuples

use core_extensions::collections::IntoArray;

assert_eq!((2,).into_array(), [2]);
assert_eq!((2, 3).into_array(), [2, 3]);
assert_eq!((2, 3, 5).into_array(), [2, 3, 5]);
assert_eq!((2, 3, 5, 8).into_array(), [2, 3, 5, 8]);

Arrays

use core_extensions::collections::IntoArray;

assert_eq!([13].into_array(), [13]);
assert_eq!([13, 21].into_array(), [13, 21]);
assert_eq!([13, 21, 34].into_array(), [13, 21, 34]);
assert_eq!([13, 21, 34, 55].into_array(), [13, 21, 34, 55]);

Implementing this trait

use core_extensions::collections::IntoArray;

struct Pair<T>(T, T);

impl<T> IntoArray for Pair<T> {
    type Array = [T; 2];

    fn into_array(self) -> Self::Array {
        [self.0, self.1]
    }
}

let foo = Pair(3, 5);
assert_eq!(foo.into_array(), [3, 5]);

let bar = Pair("hello", "world");
assert_eq!(bar.into_array(), ["hello", "world"]);

Required Associated Types
