Trait Implementations

impl<K: DataTrait + ?Sized, R: WeightTrait + ?Sized> Clone for LeafCursor<'_, K, R>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'s, K: DataTrait + ?Sized, R: WeightTrait + ?Sized> Cursor<'s> for LeafCursor<'s, K, R>

type Item<'k> = (&'k K, &'k R) where Self: 'k

The type revealed by the cursor.

type Key = K

Key used to search the contents of the cursor.

fn item(&self) -> Self::Item<'s>

Reveals the current item.

fn values(&self)

Returns cursor over values associted with the current key.

fn step(&mut self)

Advances the cursor by one element.

fn step_reverse(&mut self)

Move cursor back by one element.

fn seek(&mut self, key: &K)

Advances the cursor until the location where key would be expected.

fn seek_reverse(&mut self, key: &K)

Move the cursor back until the location where key would be expected.

fn valid(&self) -> bool

Returns true if the cursor points at valid data. Returns false if the cursor is exhausted.

fn rewind(&mut self)

Rewinds the cursor to its initial state.

fn fast_forward(&mut self)

Moves the cursor to the last position.

fn position(&self) -> usize

Current position of the cursor.

fn reposition(&mut self, lower: usize, upper: usize)

Repositions the cursor to a different range of values.

type ValueCursor = ()

fn keys(&self) -> usize
