Function stringmetrics::hamming_iter

pub fn hamming_iter<I: IntoIterator<Item = T>, T: PartialEq>(
    a: I,
    b: I
) -> Result<u32, LengthMismatchError>

Apply the hamming function to iterators

This is useful for avoiding the need to collect data before performing the calculation. a and b are mutable iterators; mutability is required as the iterator will be consumed.

Returns a Result with Ok(v) if the function completed successfully, or Err(s) if there was an iterator length mismatch.

Example

use stringmetrics::hamming_iter;
let a = "abcdefg";
let b = "aaadefa";
assert_eq!(hamming_iter(a.chars(), b.chars()), Ok(3));

assert_eq!(hamming_iter(1..3, 2..4), Ok(2));

Errors

Returns a LengthMismatchError if the two iterators are not of the same length
