Trait LendingIterator 

pub trait LendingIterator {
    type Item<'a>
       where Self: 'a;

    // Required methods
    fn next(&mut self) -> Option<Self::Item<'_>>;
    fn count(self) -> usize;
}

The LendingIterator is a version of an Iterator that can yield items with references into the lender. It is a well-known name and there are multiple crates which offer it, with differences. The needs here are small, and so rather than bring in a pre-1.0 crate, just make our own.

Required Associated Types

type Item<'a> where Self: 'a

Required Methods

fn next(&mut self) -> Option<Self::Item<'_>>

fn count(self) -> usize

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.
