Struct TypedValueArray 

pub struct TypedValueArray { /* private fields */ }

Represents an Arrow array with a TypedValueEncoding.

Implementations

impl TypedValueArray

pub fn parts_as_ref(&self) -> TypedValueArrayParts<'_>

Returns a reference to all the child arrays contained in this array. It is expected to call this method once and work on the resulting TypedValueArrayParts.

Using this has multiple benefits:

• Can reduce runtime checks for accessing and downcasting child arrays
• A bit more static guarantees, as the struct will change if a child array is removed

Trait Implementations

impl Clone for TypedValueArray

fn clone(&self) -> TypedValueArray

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl EncodingArray for TypedValueArray

type Encoding = TypedValueEncoding

The encoding used by this array.

fn encoding(&self) -> &<TypedValueArray as EncodingArray>::Encoding

Obtains the encoding instance for this array.

fn array(&self) -> &Arc<dyn Array>

Returns a reference to the inner array.

fn into_array(self) -> Arc<dyn Array>

Consumes self and returns the inner array.

fn try_as_scalar( &self, index: usize, ) -> Result<<Self::Encoding as TermEncoding>::Scalar, DataFusionError>

Extracts a scalar from this array at index.

impl TryFrom<Arc<dyn Array>> for TypedValueArray

type Error = DataFusionError

The type returned in the event of a conversion error.

fn try_from( value: Arc<dyn Array>, ) -> Result<TypedValueArray, <TypedValueArray as TryFrom<Arc<dyn Array>>>::Error>

Performs the conversion.
