Struct FunctionIterator

pub struct FunctionIterator<'a>(/* private fields */);

Iterator over the functions in a keyspace.

A Cassandra iterator is a LendingIterator because it borrows from some underlying value, but owns a single item. Each time next() is invoked it decodes the current item into that item, thus invalidating its previous value.

Trait Implementations

impl<'a> Debug for FunctionIterator<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl LendingIterator for FunctionIterator<'_>

type Item<'a> = FunctionMeta<'a> where Self: 'a

The type of each item.

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

Retrieve the next item from the iterator; it lives only as long as the mutable reference to the iterator.

fn size_hint(&self) -> (usize, Option<usize>)

Minimum and optional maximum expected length of the iterator. Default implementation returns (0, None).
