Type Toppings: Extensions for Standard Rust Types

Opinionated collection of utility extensions for several of Rust’s standard types, including:

• Result
• Iterator
• futures::Steam

Examples:

#[cfg(feature = "iterator")]
{
    use type_toppings::IteratorExt;
    
    // Map only the Some values in an iterator of Option<T>:
    let data: Vec<_> = vec![Some(1), None, Some(3)]
        .into_iter()
        .map_opt(|x| x * 2)
        .collect();
    assert_eq!(data, vec![Some(2), None, Some(6)]);
}

For more detailed examples, see the documentation for each trait and method.
