Expand description

A trait describing a mutable array; i.e. an array whose values can be changed. Mutable arrays cannot be cloned but can be mutated in place, thereby making them useful to perform numeric operations without allocations. As in Array, concrete arrays (such as MutablePrimitiveArray) implement how they are mutated.

Required Methods§

fn data_type(&self) -> &DataType

The DataType of the array.

fn len(&self) -> usize

The length of the array.

fn validity(&self) -> Option<&MutableBitmap>

The optional validity of the array.

fn as_box(&mut self) -> Box<dyn Array>

Convert itself to an (immutable) Array.

fn as_any(&self) -> &(dyn Any + 'static)

Convert to Any, to enable dynamic casting.

fn as_mut_any(&mut self) -> &mut (dyn Any + 'static)

Convert to mutable Any, to enable dynamic casting.

fn push_null(&mut self)

Adds a new null element to the array.

fn reserve(&mut self, additional: usize)

Reserves additional slots to its capacity.

fn shrink_to_fit(&mut self)

Shrink the array to fit its length.

Provided Methods§

fn is_empty(&self) -> bool

Whether the array is empty.

fn as_arc(&mut self) -> Arc<dyn Array>

Convert itself to an (immutable) atomically reference counted Array.

fn is_valid(&self, index: usize) -> bool

Whether index is valid / set.

§Panic

Panics if index >= self.len().
