Struct View 

pub struct View<'a> { /* private fields */ }

The rows of a view, in its order. Cheap to get; reading never allocates.

Implementations

impl View<'_>

pub fn len(&self) -> usize

Rows in the view.

pub fn is_empty(&self) -> bool

Whether the view is empty.

pub fn row(&self, index: usize) -> Option<RowRef>

Where the row at index (0 is first) is. O(log n).

pub fn record(&self, index: usize) -> Option<RecordId>

The record of the row at index. O(log n).

pub fn position(&self, record: RecordId) -> Option<usize>

Where record’s row is in the view, or None if it is not in it (filtered out, or its key deleted). O(log n): binary searches comparing the row’s sort values.

Trait Implementations

impl<'a> Clone for View<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for View<'a>

impl<'a> Debug for View<'a>

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

Formats the value using the given formatter.
