Derive Macro EnumArray 

#[derive(EnumArray)]
{
    // Attributes available to this derive:
    #[enum_array]
}

Automatically generate a COUNT and VARIANTS constant for enum.

Where to use:

• When you want to all variants of enum
• When you want to count of enum

Note:

• VARIANTS order is same as enum definition order. not calculate the discriminant value.

EnumAttribute: none

Variant Attribute: none

Examples

Normal

use more_convert::EnumArray;
#[derive(EnumArray, Clone, Copy, Debug, PartialEq)]
pub enum Test {
    Zero = 1,
    Three = 3,
    Two = 2,
}

assert_eq!(Test::COUNT, 3usize);
// order is same as enum definition order.
// not calculate the discriminant value.
assert_eq!(Test::VARIANTS, &[Test::Zero, Test::Three, Test::Two]);
