pub const fn singletons<I: Iterator>(xs: I) -> Singletons<I>ⓘNotable traits for Singletons<I>impl<I: Iterator> Iterator for Singletons<I>    type Item = (I::Item,);

Expand description

Generates all singletons (1-element tuples) with values from a given iterator.

The elements appear in the same order as they do in the given iterator, but wrapped in (_,).

The output length is xs.count().

Examples

extern crate itertools;

use itertools::Itertools;
use malachite_base::tuples::singletons;

assert_eq!(
    singletons([1, 2, 3].iter().cloned()).collect_vec(),
    &[(1,), (2,), (3,)]
);
