Trait ColumnIter 

pub trait ColumnIter<T> {
    type Iter<'a>: Iterator<Item = T>
       where Self: 'a;

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

Trait for columns that support iteration over their values.

Required Associated Types

type Iter<'a>: Iterator<Item = T> where Self: 'a

The iterator type returned by iter.

Required Methods

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

Returns an iterator over the column values.

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.
