Trait IterContainer

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

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

A container that allows iteration morally equivalent to IntoIterator.

Iterating the container presents items in an implementation-specific order. The container’s contents are not changed.

Required Associated Types

type ItemRef<'a> where Self: 'a

The type of elements when reading non-destructively from the container.

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

Iterator type when reading from the container.

Required Methods

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

Returns an iterator that reads the contents of this container.

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.
