Trait Iter 

pub trait Iter: CollectionRef {
    type Iter<'a>: Iterator<Item = Self::ItemRef<'a>>
       where Self: 'a;

    // Required method
    fn iter(&self) -> Self::Iter<'_>;
}

Iterable collection.

Required Associated Types

type Iter<'a>: Iterator<Item = Self::ItemRef<'a>> where Self: 'a

Iterator type.

Required Methods

fn iter(&self) -> Self::Iter<'_>

Create an iterator over the items of the collection.

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.
