Trait Implementations

impl Default for StringVectorBuilder

fn default() -> Self

Returns the “default value” for a type.

impl MutableVector for StringVectorBuilder

fn data_type(&self) -> ConcreteDataType

Returns the data type of the vector.

fn len(&self) -> usize

Returns the length of the vector.

fn as_any(&self) -> &dyn Any

Convert to Any, to enable dynamic casting.

fn as_mut_any(&mut self) -> &mut dyn Any

Convert to mutable Any, to enable dynamic casting.

fn to_vector(&mut self) -> VectorRef

Convert self to an (immutable) VectorRef and reset self.

fn to_vector_cloned(&self) -> VectorRef

Convert self to an (immutable) VectorRef and without resetting self.

fn try_push_value_ref(&mut self, value: &ValueRef<'_>) -> Result<()>

Try to push value ref to this mutable vector.

fn extend_slice_of( &mut self, vector: &dyn Vector, offset: usize, length: usize, ) -> Result<()>

Extend this mutable vector by slice of vector.

fn push_null(&mut self)

Push null to this mutable vector.

fn is_empty(&self) -> bool

Returns whether the vector is empty.

fn push_value_ref(&mut self, value: &ValueRef<'_>)

Push value ref to this mutable vector.

fn push_nulls(&mut self, num_nulls: usize)

Push nulls to this mutable vector.

impl ScalarVectorBuilder for StringVectorBuilder

type VectorType = StringVector

fn with_capacity(capacity: usize) -> Self

Create a new builder with initial capacity.

fn push( &mut self, value: Option<<Self::VectorType as ScalarVector>::RefItem<'_>>, )

Push a value into the builder.

fn finish(&mut self) -> Self::VectorType

Build a new vector and reset self.

fn finish_cloned(&self) -> Self::VectorType
