pub fn values_iter(&self) -> ObjectValueIter<'_, T>
Sourcepub fn iter(&self) -> ZipValidity<&T, ObjectValueIter<'_, T>, BitmapIter<'_>>
pub fn iter(&self) -> ZipValidity<&T, ObjectValueIter<'_, T>, BitmapIter<'_>>
Returns an iterator of Option<&T>
over every element of this array.
pub fn get(&self, index: usize) -> Option<&T>
Sourcepub unsafe fn value_unchecked(&self, index: usize) -> &T
pub unsafe fn value_unchecked(&self, index: usize) -> &T
Get a value at a certain index location
§Safety
This does not any bound checks. The caller needs to ensure the index is within the size of the array.

fn len(&self) -> usize
The length of the [

fn validity(&self) -> Option<&Bitmap>
The validity of the [

specifies whether the array slot is valid or not (null).
When the validity is None
, all slots are valid.Source§fn with_validity(&self, validity: Option<Bitmap>) -> Box<dyn Array>
