Trait Is

pub trait Is {
    // Required method
    fn is(&self, index: usize) -> bool;
}

A trait for checking if an Or value is of a certain variant by index.

Required Methods

fn is(&self, index: usize) -> bool

Returns true if the Or value corresponds to the given variant index.

Examples

use orn::{Is, Or2};

let value: Or2<u8, &str> = Or2::T0(42);
assert!(value.is(0));
assert!(!value.is(1));

let value: Or2<u8, &str> = Or2::T1("hello");
assert!(!value.is(0));
assert!(value.is(1));
