Trait EnumerateBaseExt 

pub trait EnumerateBaseExt: Sized {
    // Required method
    fn base(self, base: usize) -> EnumerateBase<Self, usize> ;
}

Extend methods for all iter::Enumerate

Required Methods

fn base(self, base: usize) -> EnumerateBase<Self, usize>

Plus the count of Iterator::enumerate by base

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

Example

use crate::enumerate_base::EnumerateBaseExt as _;
let arr = ['a', 'b', 'c', 'd'];
let iter = arr.into_iter().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".
