Provided Methods§

Source

fn enumerate_base(self, base: N) -> EnumerateBase<Self, N> ⓘ

Plus the count of Iterator::enumerate by base

Similar to self.map(|(n, elem)| (n + base, elem))

§Example
use crate::enumerate_base::IteratorEnumerateBaseExt as _;
let arr = ['a', 'b', 'c', 'd'];
let iter = arr.into_iter().enumerate().enumerate_base(2);

assert_eq!(iter.collect::<Vec<_>>(), vec![
    (2, 'a'),
    (3, 'b'),
    (4, 'c'),
    (5, 'd'),
]);

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
