Iterware

Simple middleware for Rust iterators

Just a small package, mostly for debugging purposes. Most common use would be easily printing each value in an iterator as it passes.

Think of it like a for_each adapter that doesn't change or consume the values of the iterator.

Usage

Simply import the IteratorMiddleware trait

extern crate iterware; // Not really necessary

use iterware::IteratorMiddleware;

and use method chaining to add middleware to your iterators

fn sum(values: Vec<i32>) -> i32 {
    // Type annotations added for clarity
    values
        .into_iter()
        .middleware(|value: &i32| println!("Adding value {}", value))
        .sum::<i32>()
}
